(svn r9898) -Fix (r9874): Many...
- Group protection status wasn't changed via a command.
- Group renaming didn't check group owner (and in fact changed the owner,
just like renaming a sign...).
- Added owner checks to other group commands.
- Invalidate window data after the command has been completed instead of after
the command has been sent. This fixes gui issues in network play.

(svn r9896) -Fix (r9874): when selling an entire train, decrease the number of vehicles in the group only once
