Get rid of config adapter.

This change involves many classes because the adapter was relied upon
heavily throughout the project. The change is motivated by the fact
that the wrapper created more problems than it solved. Those problems
(listed here) are solved by this commit. Some classes have undergone
notable changes (e.g. ArenaRegion).

- The config-file will no longer overwrite and regenerate itself
  seemingly randomly.
- The config-file will now save correctly when setting points and
  expanding regions.
- The "no class items in lobby" problem has been fixed.
- The "must be inside region" problem has been fixed.
