Fix all warnings
Add 'source selection' dialog

Add a 'source selection' dialog to replace the 'enter a name' dialog.
This new dialog allows you to make new instances of pre-existing sources
so that you can add a pre-existing source to a different scene, or in to
the same scene more than once.

Also started implementing locale.

Comtemplating switching to JSON-based locale later, so we can add things
like descriptions/disambiguation, and so we can use jansson's built-in
hash table when doing the string lookup.
Move display capture texture update to video_tick
Move display stream update handler logic out of init_display_stream
Reduce lock holding time for display stream and guarantee update

With the previous locking strategy some display captures would sometimes
not process multiple frames in a row if multiple display captures were
active
Add log message for dropped display stream frames
Basic UI:  Fix scene/source reference counter

The 'how many scenes is this source in' reference counter used
in the basic UI was not being decremented.
