Speaker & Talk Pages
Added arrows. And their SVG source files if we need to make them bigger.
Renamed files to compile
Turned About screen into Sponsors screen.  Next to create About screen in the menu,
Sponsors now don't disappear after moving between various screens
Added the about page as a tab in the main screen.  We can't have it as a menu button item because Android has deprecated the menu button in favour of the action bar.  To have in the action bar we'd have to have a one line action bar always visible. Ugly.  I'd prefer the sponsors to be in the About page, but the team didn't like that.  This is the only other option I can of.
