Allows the ability to get the last rendered texture of the main output
view.

[Qt 5.11] Include 'QAction' in 'scripts.cpp' to fix a build failure.

The filters array should not be accessed without locking the filter
mutex.  This locks the filter mutex, grabs a reference to the first
filter, unlocks the mutex, renders the filter, and then releases the
reference.

Vth264 fixes

The "Delete" shortcut is already set in the UI/forms so the old code
would only change shortcuts in macOS.

On windows, the "Always on top" state can safely be used without closing

Holds the clipping flash for one second to better indicate that clipping
is occurring.

Add Selected and Hidden Array Values

Let developers get and set whether items in an editable list are hidden
or selected. May be useful in when editable lists are modified and
handled in a callback. Especially when edit button callbacks are used.

Due to the commit 34c14829, source loading is now deferred
to after OBSInit(), which would cause saved scene/source projectors to
no longer load on startup.  This fixes that issue by moving the
OpenSavedProjectors call to OBSBasic::Load().

Save Windowed Projectors on exit

When an user launches a multiple instance of obs and don't use the -m
flag, wait until the confirmation to launch to create a new log file.
This avoids a short log with no information when using the Help ->
Update Last Log.

The log output of the travis CI for macOS is unreasonably large.  This
reduces the verbosity of the output and reduces the size of the build
logs significantly.

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.
