Bug 883017 - Send MMS with UTF-8 charset; r=gene.lian

Some MMSC seems to be doing bad things if we don't encode/specify the
correct encoding: SFR and Bouygues Telecom delivers UTF-8 destroyed,
while Free Mobile and Orange did a good job. Setting the charset to
UTF-8 makes those four carriers (and probably a lot more) happy.
