Themes: Load correct common resources

In order to support theming separate packages we need to make sure

the system wide theme's common resources which is incorrect for
package level theming.

Allow granting permissions based on signature in <allow-permission/>

This patch allows us to either specify a sharedUserId or a package
signature to use when granting the specific permission.
