Minor patch 0.7.2

Reduced enemy health scaling (especially on hard mode). Many bosses were pretty much impossible by the 3 hour mark on Hard mode. I want it to be a challenge but not impossible, at least not at the 3 hour mark.
Added 10 levels to the health upgrade. The total amount of bonus health it gives at level 30 is 1,000, but the cost scales up sharply. Bosses like Werebear will eventually scale up in health so high that they'll get on top of the central objective, so this will help tank them a little bit longer.
Nerfed "Deal with the Devil" relic by 100% of the gem value. It turned out to be very overpowered, especially if obtained early.
Nerfed "Divine Intervention" relic's power growth with multiple stacks. There's too few relics in the game, so it's a bit too easy to stack these.
Fixed a bug where Contract Work was not applying the upgrade correctly.
This is a bit technical, but I'm now using an infinitely scaling number type to represent scores and gold. This should hopefully mean an end to the negative score/gold collected bug. The max amount of gold is kept at its old value however. (The Gold/Minute label hasn't been updated to use this yet and may still be affected.) Please let me know if you see any issues.
