Settings: updating policy list after switching mobile data switch

Removed unnecessary call to updatePolicy() in the mDataEnabledListener since the setMobileDataEnabled() method already calls it.
Calling updatePolicy() with refreshCycle to true, so that the "change cycle..." option is enabled/disabled correctly

On-the-spot preferences

Allow for handling of resetting multiple preferences individually.

Present the user with a list of active on-the-spot preferences to
choose from.
If a preference dialog was never presented to the user, it will not
be available for reset.
If only one preference is currently active, a simple reset dialog is
presented (current existing dialog / no list)

PS1: Initial commit
PS2: Use defined strings instead of decoding the SETTINGS_TO_RESET variables.
     This allows for string translation.
     String names should be equivalent to the SETTINGS_TO_RESET variable.
PS3: Add some error checks
