When embedding external files. the same file is queued twice for peak-file
generation. Since there are two peak_thread_work threas in SourceFactory,
this can lead to inconsistent/missing peaks.
TODO: fix the actual cause, duplicate call to setup_peakfile():

Not doing so can make source or object files appear multiple times in
the list of files to be compiled or linked, e.g. when doing './waf build
install', subsequently leading to linker errors.
bug:
1) freeze a track
2) Session Cleanup > Cleanup unused sources
2a) confirm playlist deletion
3) quit, reload -> track is no longer frozen
because _freeze_record.playlist is missing.
session is in an odd state.
Grouped "checkbox" preferences together, reducing visual clutter.
Some widget settings affected the visibility/sensitivity of other widgets.
In some cases they were not adjacent; this has been fixed.
Added some additional grouping headers.
