* Sanity check pane settings. Retrieve update main window size from
configure-event callbacks rather than trying to retrieve size from
a possibly destroyed window (by window manager). Allow window manager
complete discretion in window placement. (LP: #764082)
* Revise size parameters passed to poppler page render call. (LP: #764069)
* Revert the slide loading function to run synchronously
rather than using python threads. (LP: #749848)
* Handle case where web page has no title. (LP: #751019)
* Correct color setting in tags in Classroom.py and
NativeChatroom.py (LP: #716937)
* Add desktopcouch dependencies. If desktopcouch related package dependencies
are corrected this will no longer be necessary. (LP: #727232)
