Hey all, the budget screen is finally coming together! This commit adds a budget screen and tracking of financial transactions and storing of income/expense records on each slave. The old upkeep screen is now a subscreen of the budget screen, found under "Slave Maintenance." The new screen can be found where the old one was, the upkeep link.
I go into more detail on this on #401 (closed).
Hopefully everything merged correctly. I'll keep working on bug fixing (currently chasing a missing expense that's divisible by 100) but I'd appreciate more eyes.
Edit: I don't have a long save, so if anyone could check if "upkeep" is the same on the master version and this one on the same save. I had to reorganize economyJS quite a bit to make this work, but it should still be the same results.
