* The option will enable monospaced fonts for all data displays, like
the list of events, API calls, etc as well as pipeline displays, entry
of filename/directory in the capture window and many other places.
Pure UI labelling etc mostly still stays as a serif font.
* A few sizes of controls were tweaked (like headers in the pipeline
windows) so that they didn't just barely overflow with the larger
font.
* While looking at this, it became obvious that buffer viewers and
constant bufferviewers should always display in monospaced regardless,
so that has been changed.
