Add a new algorithm to calculate the true-peak. It implements the
Whittaker- Shannon interpolation from four samples to create 4
intermediate samples (5 x oversampling) inbetween the middle two
samples.

With 4 samples and 4 intermediate samples the algorithm can be
implemented as a 4x4 vector-matrix cross product, which is ideal for
SSE.

I've also replaced the sample-peak algorithm using SSE as well to
improve performance.

Adds an alternative means of isolating the CEF initialization process
from Qt's initialization process.  This is an unpleasant hack, but is
far more preferable than isolating the entire browser plugin to a
separate process and overly complexifying the browser plugin to the
point to where no one wants to touch the plugin or contribute to it.

Allows the ability to perform multiple actions that would normally save,
and defer the save until all of those actions are complete.

Closes obsproject/obs-studio#1231

Adds the ability to upload crash reports, making it easier for users to
give us crash data.  This should be considered a temporarily solution,
as automated crash reporting should be the ideal solution as soon as
time permits.

Allows the ability to get log files from other configuration
subdirectories (i.e. "%appdata%/obs-studio/crashes")

Prevents simple output mode from getting stuck on an encoder that may
not be available suddenly for whatever reason (system device changes,
driver issues, etc).  If the encoder is no longer available, falls back
to x264 to ensure that the user can continue to use the program.

The decay rate of the audio meters can now be selected in the audio
settings.  The values are:

- "Fast"   (OBS default, 40 dB / 1.7s)
- "Medium" (Type I PPM,  20 dB / 1.7s)
- "Slow"   (Type II PPM, 24 dB / 2.8s)

Jim note:

- Refactored code significantly
- Added a context menu option to exclude specific scenes from projectors
- Made it so multiview projectors update when scenes are
  added/removed/renamed
- Increased text quality
- Removed the color sources and replaced them with simple solid
  rectangles
- Increased the border size of "program" and "preview" scenes in the
  lower scene list

Closes jp9000/obs-studio#1068

Fixes an issue where quick transitions would not function if the scene
has a transition override set for it.

If a preview projector was created in normal mode, it would become a
studio projector in studio mode.  The window title of the window
projector would reflect that it was in fact a preview projector and not
a program projector.

Allows the ability to override what specific transition a scene may use
when transitioning to it.

(Original proposal by cg2121, reworked by Jim)

Closes jp9000/obs-studio#1052

The studio mode program view projectors used the wrong saving mechanism.
The save data was copied from the source projectors, which were
dependent on string values, where as it should have been using a boolean
true/false value for specific monitors.

This commit adds a checkbox to general setting to allow users to enable
a vertically oriented layout for studio mode.

This commit addresses mantis issue 827:
https://obsproject.com/mantis/view.php?id=827

Closes jp9000/obs-studio#1072

This commit allows a user to create projectors for the preview scene
instead of the program/live scene.

Close jp9000/obs-studio#1071

This adds the ability to switch to a scene by double-clicking it when in
studio mode.

(Edit by Jim: In case this change is undesired by the user, this has
been changed to be an option in general settings; disabled by default)

Closes jp9000/obs-studio#1029

This adds the ability for users to change the names of audio sources
from the mixer including desktop and mic/aux sources.

Closes jp9000/obs-studio#1055

Allows the ability to hide/unhide sources in the mixer that the user
doesn't care about or doesn't necessarily want to see (such as video
sources that have audio but don't have any audio playing).  If all
sources are hidden, the user can right-click the mixer's empty area and
choose "unhide all" via a context menu.

Closes jp9000/obs-studio#1002

Changes the UI to an adjustable user interface, allowing the user to
fully customize how the scenes list, sources list, the mixer,
transitions, and the buttons are oriented on the main window window.

(Edit by Jim: Added a check to make sure that the browser source exists
due to the fact that it's technically optional)

Closes jp9000/obs-studio#905

(Edit by Jim: Removed "Fullscreen Preview" because that's already sort
of served by the normal fullscreen projector option via the preview
context menu)

Closes jp9000/obs-studio#846

Fixes a bug where the individual drop-down lists of each quick
transition would not have the correct available transitions listed if
transitions were added, renamed, or removed

Shows performance stats, and streaming/recording stats, and helps warn
the user when they have less-than-optimal values with coloring on the
values (e.g. yellow when getting low on disk space, red when getting
really low)

The auto-configuration wizard is designed to allow first-time or
novice/uneducated users or to set up video and encoding settings in a
very quick and easy way.  It'll automatically perform a bandwidth test,
and/or test the user's video settings to determine the most ideal
settings for streaming and recording (assuming a 1-pc setup).

Closes jp9000/obs-studio#841

Closes jp9000/obs-studio#860

This adds an option to the general settings to save the opened
projectors on exit.
