GUI changes, currently broken, stashing on this branch.
Convert from ribbon to AUI; this works better
Instead of trying to use a ribbon bar, now using an AUI Toolbar (and overall AUI window manager) for the core browser. Next steps are getting things set up properly on startup (so core/view/filter are already selected, and persistent), moving the wall of buttons, and using the "what's being displayed" statusbar-like item to better effect...
Use PersistentControls to keep window positions etc.
(This is instead of using Config and trying to roll our own). Next up: some code cleanup, doing something sensible with the wall of buttons. Then, a statusbar to tell you all of what's in the grid...
Fixed the os-dependent path splitting problem in datastore.py, and removed the eclipse project files from the repo.
