Who's Frank? No clue.

CHANGES

+ Added floor boards (for real this time)

- each multiplies newly bought buildings after purchase for 10,000, 50,000, and 100,000 respectively.

There are quite a few issues related to floor boards that need to be fixed, so expect that over the next few days. I also really need to fix balancing, as it was already kind  of janky before, and I feel floor boards didn't help. If I had to give my honest thoughts on floor boards, I'm not a huge fan. They kind of fall into the random = funny area that I want to avoid. Throw in the fact that I'm Probably going to need to overhaul the system at some point, and I'm not to thrilled. But they'll work as a placeholder upgrade system for now.
