Mms: Add "Insert contact info" back

Bring back the ability to insert contact info (Phone numbers, Email addresses,
Events, Postal address and Website), in a SMS or a MMS, as a text.

Compared to gingerbread/CM7: - several info can be inserted thanks to checkboxes
                             - no more adapter (not really needed)
                             - Event info added
                             - feature is under Menu, not Add attachment

    * Patch Set 1: initial commit
    * Patch Set 2: corrections, better strings, util/DateFormat.java added
    * Patch Set 3: Cleanup
