Handle multi-user whiteboard for solo presenter

Recording: Don't use string interpolation when generating commands for slide conversion

Adjusts the user interface to keep coherence when activating the multi-user
whiteboard while there is only the presenter in the meeting.

Just want to make sure that we don't get any bad filenames sneaking in
and causing havoc.

Recording: Audio processing changes to reduce audio desync

This incorporates only the audio desync related changes from #11626
* Add the aresample filter with async option to fill in timestamp gaps
* Use the libopus decoder for opus audio instead of ffmpeg's builtin
  decoder

This gives the following advantages over the previous code:

* The ffmpeg input filters are loaded from a filter "script" file instead
  of passed on the command line. This fixes some cases of recordings
  failing to process because the ffmpeg command line generated for the
  audio processing exceeded the max command line length limit. (Although
  that only really happens due to BBB bugs...)
* Use absolute positions when trimming audio segments for cuts.
  Previously segments were trimmed to the length of the segment, and the
  results were concatenated. There's some possibility of accumulated
  errors in the segment lengths causing audio desync over time. The new
  code incrementally concatenates the segments, and cuts each segment
  end based on the absolute time since the start of the meeting, to
  avoid error accumulation.

Replaced keepEvents with defaultKeepEvents and meetingKeepEvents
