[ardour-dev] latest CVS commit

[Paul Davis]

   * fix for a nasty panning SNAFU: if a session was
       incorrectly saved with the wrong pan state
       due to a bug, it would lead to memory
       exhaustion when loading the session. Great
       thanks to Paul Symons for his help in 
       remote debugging this. Go Cornflake Girl!

   * fixed missing initial saved state in Locations
       object (undo after adding a marker removed
       all location/range markers)

   * insert + embed now obey multi-file selection

   * ardour/gtk: 0.519.0
     libardour: 0.819.1
