* When no servers have been registered, automatically open the
"Register Server" dialog on startup.
* Fixed a minor bug which didn't automatically set the correct
default values for some features introduced in the prevous version
when registering a new server.
* Added an "Unlimited" option for the Automatic SELECT Limit option.
* Enabled plugin support.
* Fixed a bug compiling MySQLCC with Qt < 3.1.0.
* Fixed a bug which automatically used the default unix socket when
"localhost" was defined as the servers hostname. It now uses the
unix socket if the hostname is "localhost" and the port is 3306.
