This converts the advanced audio window to use
a ui form, so it is easier to modify in the future.
This also fixes sizing issues with the control widgets,
as before the audio tracks would be clipped, because the
widgets in the window were too wide.
This limits the length of the name label in the advanced audio
dialog to 80 characters, so the dialog doesn't get too wide. If the
name is truncated, "..." are added at the end of the label, and the
label's tooltip is set to the full name of the source.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
Audio controls in OBS Mixer and Advanced Audio Properties window are not
sorted at all. Every time OBS is restarted they get shuffled (Jim note:
This is due to json object hashing). The order of these controls is
additionally not consistent between the mixer and the advanced audio
properties window.
