Minimum size is changed to 700x512. I arrived at this number from testing
the minimum sizes that I felt the settings UI was still perfectly usable
and readable. Any smaller, and things became difficult to see and adjust.
As a note, this does increase the minum width of the settings window, as
the previous minimum allowed you to cut off objects and render the window
too small to be usable.
The audio subsystem of windows is by default configured to lower the
volume of other things while a communications device (mic) is currently
active. This patch prevents that from being enabled with OBS. If the
user needs audio ducking enabled again for whatever reason, there is now
an option to re-enable it in advanced settings.

Adds the ability to use a specific prefix and/or suffix on replay buffer
filenames to distinguish them from normal recordings. Defaults to
having the prefix "Replay".
Replay buffer and recording should be separate in case the user wants to
start recording from a specific point rather being forced to reconfigure
for regular recording.
Creates a new button on the main window below the recording button for
turning on/off the replay buffer.
