Improved client_hash_check

- Added option to disable hash check by GM group_id (specify 'disabled'
  as hash for a certain group_id to let them log in with any client,
  even if client_hash_check is enabled
- Updated and reworded related documentation for the feature, following
  user feedback about certain parts being incomplete or confusing.
