- Checks for previous instances by using the FindProcDLL NSIS plugin

- No longer allows ignoring if there is a sharing violation.

- Added version information section to allow friendly description in
  the UAC elevation prompt.

- Kill lingering instances of cef-bootstrap before installing.

Allows getting a translated string for the current module, returning
false if no string available.

Allows manipulating and modifying the front-end via plugins.

Allows using the functions outside of the file they're in.

This allows using the functions via Qt message queue.  The reason for
this is so a frontend API can queue these functions to call safely from
another thread.

Closes #613 & #614

Add Windows bitness (32/64-bit) to log file

This is to prevent confusion both when prefixing commits and when
reading the directory structure for the first time.

This adds a fps indicator to the status bar, to the right of CPU usage.

Closes jp9000/obs-studio#585

Allows getting the current active framerate that the core is rendering
with.  This takes in to account any rendering lag or stalls that may be
occurring.

Added: "US-East: New York - 2"
Modified: "US East: New York" to "US-East: New York - 1"

libobs: Set core signal handlers to NULL after destroying

Fixes https://obsproject.com/mantis/view.php?id=595

Closes jp9000/obs-studio#563

Fixes an issue where the shutdown separator in the log file would always
appear even when the user decides not to shut down the program after
clicking close when still streaming/recording.

This adds a system tray when enabled. There is also a option to minimize
to the system tray when the app is started.

Closes jp9000/obs-studio#595

The code to enable/disable the profile menu along with
incrementing/decrementing the sleep inhibitor was duplicated more times
than necessary.

Allows usage of jack on OSX (as well as windows later).

Closes jp9000/obs-studio#587

obs-filters: Fix step size for surpress level of noise surpression filter

libvlc_media_new_path implies a file.  To get media based upon URLs, use
libvlc_media_new_location.  Additionally, if using a URL, it's best to
give it some playback caching/buffering, at least 100 milliseconds.

Closes jp9000/obs-studio#590

Outputting a human-readable error message on library load failure makes
it a little bit easier for plugin developers to determine why a plugin
library may have failed to load (such as missing dependency), rather
than having to look up the error code each time.

Closes jp9000/obs-studio#596

Previously, for an unknown reason p-frames were marked as highest
priority along with i-frames (keyframes), which means they could not be
dropped.  This would cause a problem where if for whatever reason
there's too much congestion, data would continually buffer.  This fixes
the issue by dropping p-frames at a separate (higher) threshold than
b-frames.

P-frames were initially set as highest priority to prevent them from
being dropped (not sure what the rationale was behind this), but this
caused a problem where if there's too much congestion for whatever
reason data will continue to stay buffered, so to prevent this p-frames
should be droppable.

Measures packet data rate and sleeps to prevent data from going above
the set data rate.  Uncomment the TEST_FRAMEDROPS macro, then set
DROPTEST_MAX_KBPS to the desired kb/s (for example 3000 for 3000
kilobits per second), and then it will limit the data rate to that
specified amount, forcing the thread to sleep to ensure it can only
output the desired data rate.

This new trick forgoes the use of patches and allows the ability to use
shared GPU resources despite being a Direct3D 9.0c context.

Causes issues with certain servers that don't parse it properly and only
expect a specific string.

Use the RTMP onMetaData to get the OBS version instead when possible.
