refactor the menu, the mi2str() implementation, and tests
Instead of a sub-menu for changing the IMSI, just offer a dialog with the
current IMSI pre-filled in an edit field.
"Show IMSI" becomes just "Change IMSI" without changing anything.
Change mi2str() so that it simply returns a byte[] of the right size.
Test new mi2str()
