media-session: sanitize name and nick

Browse source 
Replace unwanted chars in the name with _. This makes it compatible
with pulseaudio names and avoids problems with regex.
Replace unwanred chars in the nick with ' '. This ensures JACK
clients don't receive ':' in the device names, which cause it to
fail when parsing the ports.

See #714 and #130
