Introduce 2D All Apps and other support for sapphire-class devices.

AllAppsView is now the 2D, GridView-based version (very
similar to classic Launcher); AllApps3D is the
RenderScript/Rollo implementation.

TODO:
 - some mdpi assets are not in fact mdpi
 - related to above: static wallpapers not working yet
 - add dynamic selection of 2D/3D AA; currently you must
   choose one at build time by picking the appropriate class
   in all_apps.xml (see separate CL for sapphire overlay
   that does this)
