Add the Allow Rotation setting to Launcher3.

This CL adds a Settings activity along with the code needed to provide
a "Allow Rotation" setting to all phones and tablets. This setting is
set to false for phones and true for tablets. On changing the setting
from unlocked to locked, the launcher (and the Settings activity)
will get locked to the orientation the user was in when he disabled
"Allow Rotation". This is consistent with how the natural rotation
feature of Android works.
