Dev Status

As it turns out, there's already a "user" tile integrated into the stock ROM masquerading as a "multi-user mode" switch.  It was a simple matter to edit the Settings app to enable adding the tile to the active quick settings list.  From there, all it took was a quick edit to the avatar drawing code (which was programmed to put the user image into a circle); duplicating, modifying, and renaming an initialization method in the main quicksettingsbutton class; and adding a modified/custom tile layout specific to the user tile.  Good times.  Just a couple more things to do and then I'll be ready to start BETA testing.
