Subject: [PATCH] Use libidn for stringprep

Which actually validates according to spec instead of just being lazy.

For example, this means an invalid MUC nick will actually be caught by the app
and reported in the UI rather than trying to send it to the server and giving
and obscure message about "nick already taken".
