Mms: 'Open' in QR menu & resume sleep after sending msg from lockscreen

This adds an 'open' to the qr menu which allows you to enter
the current conversation(in turn clearing notification and
marking read/seen)

Second feature is optional and allows the device to be turned
back off when launching qr from lockscreen after its been relocked.
(device off->on->check notifs->use qr->relock->screen off)
