Themes: Only process themes that are applied during boot

Currently, the PackageManagerService will process all themes and
ensure their resources are compiled and available to the system.
This is highly inefficient and can bog the system down when booting.

This patch will only process the themes that are currently applied
durring boot and lets the ThemeService take care of queuing up the
others for processing.   This reduces boot time considerably,
especially when the user has many themes installed.

Fix for "volume buttons change two volume steps per click" bug

This bug happens on all devices since CM9 or CM10 times.

To reproduce:
1) disable Settings/Buttons/Playback control
2) start music playback
3) turn off display
4) click on the volume buttons

When "Playback control" is enabled, the volume changes on the button up
event of short clicks only. When it is disabled, it changes on both
button down and up events. This fix cleans up the code and makes the
volume change only on button down when "Playback control" is disabled.
