More corporation renaming

Just renaming files / functions. Industries are the static categories that divisions can operate within, divisions are the actual branches of the company. A lot of stuff was still written as if Industries are the actual branches of the company, which is even less accurate now that a corporation is allowed to have multiple divisions operating in the same industry.

Also removed the incorrect tooltip description of what tea does (it's now just a flat +2 increase)
