rtmp-services: Add Restream.io Los Angeles server

Adds an option to the aspect/scale filter to undistort the center of the
image when scaling from ultrawide to wide.

Closes jp9000/obs-studio#762

This algorithm reduces scaling distortion on the center of the image
when scaling from ultrawide to wide.

(Jim: edited effect files to prevent an impact in performance for
standard scaling.  Now effectively generates an extra pixel shader, and
the extra code is only applied to the DrawUndistort technique, while the
original Draw technique is unaffected due to the compiler automatically
removing unused code branches via the hard-coded boolean value)

From jp9000/obs-studio#762

On linux, the main window isn't immediately set to a native widget, so
the call:

connect(windowHandle(), &QWindow::screenChanged, displayResize);

on line 189 will fail, causing the preview widget to not properly resize
when the main window is resized.

Closes jp9000/obs-studio#776

UI: Add more command line options

Fixes bug 617 on mantis.  Scaling the source manually in the viewport
wouldn't work properly when the source is flipped horizontally or
vertically.

Closes jp9000/obs-studio#751

Closes jp9000/obs-studio#748

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

(Note: Fixed conflicts -Jim)

Closes jp9000/obs-studio#743

Prevents the program from unintentionally quitting if the program is
minimized to the task tray and the user closes all projectors

Closes jp9000/obs-studio#737

Hides dialogs when minimizing to tray, and shows again when restoring
from tray.

500ms is a bit unnecessarily low.

From 0.0 (not congested) to 1.0 (completely congested/dropping).

Fixes an issue where non-english debug text wouldn't display correctly
in the debugger output on windows.  Also, only output debug text when
actually debugging.

rtmp-services: remove shut down services

Update video ingest servers for Vaughn Live.  Also split Breakers.TV
into its own since it is possibly becoming its own entity soon.

CI: Build VLC plugin for OSX on travis

When setting up a build for the first time on windows, makes it so you
no longer have to run cmake twice:  once to build, then once again with
the COPY_DEPENDENCIES box to ensure dependencies are copied.

Closes jp9000/obs-studio#768

CI: Build Windows version and upload artifacts

CI: Update permissions on CEF app plist before packaging

obs-browser: Update browser ref

Currently this build is still missing the following plugins:
enc-amf
obs-browser
win-ivcam

CI: Move browser source before building app

The buildapp.py script was modifying the CEF.app when we don't want it to. It was also packaging the plugin inside the OBS.app so the app was not using the one under /Library

CI: Add in inital appveyor config

This reverts commit f4d7f0cb.

Never thought a revert of a revert would happen.

Fixes a hang on startup.

Due to the fact that people follow terrible guides that ignorantly
recommend opencl, the "opencl" custom x264 option was blocked.  However,
because some people still apparently want to use it, it's being renamed
to "opencl_is_experimental_and_potentially_unstable" so that anyone who
uses this option realizes that they should probably think twice about
using the option rather than just follow some terrible guide that tells
them to use it.
