Small localization update

Reduced laboratory cost

Some small tweaks

Small balance patch for something, blatantly, and absurdly, overpowered.

A few balance nad QoL tweaks

Some tweaks for the strategy layer

Cleaning up an awkward implementation

Slight tweaks and user QOL improvements.

A few tweaks at Ronar's request.
Relocalized the mission difficulty/enemy activity labels.

Plasma Edged and Laser Edged Swords tweaked to compete with Coil Swords instead of magnetic swords, but are now more expensive and difficult to obtain.

Game will now check at each month end to see if the GTS soldier training rank should progess, which now scales up to a maximum of Sergeant over the campaign's duration. This makes replacing soldiers in the endgame a bit less impossible.

GTS Class unlock costs tweaked.
