Only show ART information if switching from dalvik to ART

We do not want to confuse users with a big information dialog, if
they change from ART to dalvik as dalvik is still the official
solution, supported and considered safe.

Add option for switching between UMS and MTP/PTP mode. (2/2)

This adds support for switching between UMS and MTP/PTP.
Settings part (this part) adds option in USB settings (statusbar/notification drawer) for enabling UMS,
and adds setting in Storage menu to enable / disable UMS, this since the USB settings page disappears when enabling UMS.

Forward port from cm-10.2, adjusted for 4.4
