- Implemented permission system management inside the game

- changed @chperm to @setperm to avoid confusion with channel commands
- added @setgroup command for adding user group permissions
- Moved permissions/group setup into settings file to allow admins to tweak without going into evennia engine.
- Add all new players to default permission group (defined in settings)
- Defined a basic group hierarchy, removed permission 'genperms.builder' in favour of a group named builders instead, containing all relevant permissions.
- Filtered out all django's automatic permissions in @setperm/list to make permission system more controlled by admin.
- Probably fixed bug that caused new users to not be signed up to channels (more testing needed)
- Added Exception handler in unloggedin method create, this was killing tracebacks upon user creation.
