Adding contacts normally and via search-results works slightly differently
in MXit. The 'Invite' button on the search-results window pops-up the standard
"Add Buddy" window, and so the prpl doesn't know what type of invite to
perform.
To get around this problem for now, we'll encode this in the search-results
userId and the prpl can detect this and perform the right type of invite.

doxygen and graphviz dot, then running "make docs" in the
source tree. The documentation will be in the docs/html directory.
