Settings/Wifi: Add support for Ad-hoc (IBSS) networks

If the WLAN driver can support IBSS mode, show Ad-Hoc (IBSS) networks in the
list of available Wi-Fi networks and allow to connect to or create new Ad-Hoc
networks.

This is merged and ported from CM-10.2, where it was split up into 3 commits.

Fix resource IDs being added to the android namespace

Using @+android:id/some_id will create a new resource ID
with package ID 0x01 rather than 0x7f, for non framework
packages, if "some_id" does not already exist.

Fix the APN editor fix

The APN creator puts its data in a Bundle, not an Intent. Get the
operator identification argument from the right place to avoid
attempts at creating networkless APNs
