Merged keep_recording branch

This branch fixes the issue of your recordings ending every time the
network stream is disconnection.

This commit is a squash of the following commits on the branch:

    tweak the button positions a little bit
    Added OnOBSStatus plugin callback
    Enables plugins to recreate the (LIVE + REC) display
    Skip ReportStreamStatus callbacks if there is no actual stream
    Fix the status bar for real this time
    Make the status bar keep updating when not live
    Fixed exit cleanup while streaming/recording
    Fix Stop() behavior and stream status message
    Continue recording even if the stream goes offline
    Requires setting KeepRecordingOnStopStreaming to 1 in global.ini to test
