Add contact sharing through SMS

This extension shares contact information through SMS message, using a text data
encapsulation protocol, and facilitates receiving and saving this kind of
information by opening the New Contact activity with its fields already
completed. Also, when sharing a contact the user can choose which information
to share through the application.
Contact sharing was integrated in the Mms by inserting classes:Encapsulation
in mms.model, ArrayOptions, ListItemComponents, OptionsList and Dialog in
mms.ui, CheckIsContact and ReceiveContend in mms.transaction and by merging
sending the contact information in ComposeMessageActivity and receiving the
information in PrivilegedSmsReceiver.
