Issue: Compatibility with vB 4.1.11

In vBulletin 4.1.11, the previously separate option of the vBulletin Mobile Style has been added as a second Master Style. This makes it easier to do some things, but likely some templates need to be updated, since the style no longer inherits from the original style list (it has its own hierarchy). The install and upgrade processes need to be updated so that the mobile style is included and that templates are uploaded to the correct master style.

Completed for VaultWiki 3.0.17.
