- Cleaned up elements in ChooseLevelMenu and ensured onscreen button had correct command

- Ensured there's always a level selected by default on the chooseLevelMenu
- Added a small delay to try and ensure the level/server config tab key hints align properly
- Added logic so you can't swap to server config page on chooseLevelMenu if in single player mode
- Added server description to server details line on JoinServerMenu
- Ensured programmatically added elements aren't saved out if GUIs are edited
- Fixed back-out prompt in OptionsMenu properly backs out so it doesn't break menu nav
