Noticed the new difficulty files were making it a bit too easy by giving the player a lot more health, so I toned it down a bit, and normalized all the difficulty files. Now, all difficulty levels are identical.

Adjustments to the cost and cap for new special call-ins.

/sigh fixing the thing I broke when fixing the properties files...

Updated some Properties files that were causing crashes due to new defines secretly implemented. But I guess since the Devs never tell modders what they changed, everything is sort of a secret...

A few minor corrections in the research screen.
