* BRoster::Launch() cannot be used (yet), as it pre-registers the
application we're launching, and that won't work for the registrar or
anything else until the registrar is up and running.
* Renamed B_GET_LAUNCH_CONNECTIONS to B_GET_LAUNCH_DATA.
* Add the team ID to the get-launch-data reply.
* Added BLaunchRoster::GetPort() for convenience.
* Removed some superfluous debug output, but temporarily dump all stdio
to /dev/dprintf (ie. the syslog).
* Made job matching case insensitive (as MIME types should be).
