Installer UI updates and lint fixes
This updates UI classes of the installer to reflect the changes of AOSP's installer and fixes some lint errors.
* No more differentiation between personal and device permissions (didn't even notice that there was a differentiation here...)
* Icon for "other" permission group
I carefully merged only the changes from AOSP that are related to us and decided against maintaining different versions of the AppSecurityPermissions.
There will be more changes and discussions to the installer UI coming in the next days.
