Subject: (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.
