Return system theme when SecurityException is caught.

Isolated processes cannot access content resolvers so a SecurityException
will be thrown when calling getBootTheme.  This catches that
exception and returns sSystemTheme.

CM11 Themes: Ensure customTheme is not null.

The configuration retrieved via getConfiguration() sometimes contains
a null customTheme which results in the theme returning to holo when
applying a component such as icons.  Icons will change but styles
and fonts would return to the default.

CM11 Themes: Fix how common resources are found

During the boot process, application info may not be fully
available and createPackageContext can throw a null pointer which
causes a theme's resource-cache to be cleared.  If this theme is
in /system/app or /system/priv-app the theme will still be installed
but applying it will result in styles not being applied.
