Fixes in accordance with Griatch's suggestions

Made a few changes:

- Put the helper functions above the typeclasses in the module.
- Changed the example command given and changed the default clothing type 'body' to 'fullbody', so that clothing types aren't taken to mean wear locations by default
- Added note to CLOTHING_TYPE_AUTOCOVER explaining that only clothes that are already worn get auto-covered
- Fixed a traceback issue in CmdGive
