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)
