Update for MBOptionScreen 2.0.4.

If you're still on 1.1.15, don't update this either.

1.2 stable and 1.3 beta compatible.
Features:
- In-game options menu and configuration
- Significant performance Improvements
- Weapon preservation is now by weapon class (no more replacing spears with scythes or swords with hammers)

Update for MBOptionScreen 2.0.6**

Hopefully the last time we have to do this :D

Minor tweaks and bugfixes.

Both this and the previous version are 1.2&1.3 compatible.

MCM 2.0.10 update

Shouldn't break just because MBOS (MCM) has updated anymore.
