Lang/Credits in Server window instead of just Registry

Changing languages while connected to a server didn't exhibit any odd behavior, some people might not entirely notice JUST on the registry window. So it makes the sim a bit more user friendly to always be there.

Then since Credits are being updated to add PkParaiso and such, I though we should make them a bit more prominent. 

I split it just in case you didn't want to change this, or wanted it done differently.
