Build 0.2.3.1

** Major Changes ** The Shift system has been added in. You can now define predefine groups of employees, and set active groups at once. You can also set a defined shift on a job loadout, to change employees based on specific needs.

Note: this system, like the party system, is still likely to change quite a bit in the future

**Bug Fixes ** Worker cap bonuses were being reset on retirement until the game was reloaded due to a misordering of operations while resetting the game, this has been fixed.

Druids were not being generated with inherent Mana. This is not retroactive to existing employees.

A CTD error tied to a specific hardware config has been fixed.
