Wi-Fi: Manage Wi-Fi AP priorities

AOSP has a basic LRU priority for Wi-Fi networks (last connected has more priority).
This changes added the ability of graphically set the priority of any of the configured
Wi-Fi networks through Settings -> Wi-Fi -> Advanced Settings -> Wi-Fi priority.

Port from cm-10.2:
* Added ic_grabber icons
