FMod - Actual Bio Menace Support

Ah, today I finally got to write the new unified dependency file loader. This was actually a lot easier than I expected. There were about three pages of code that the function replaced, and it is about two pages long. The Open and New menu items now call this with a minimum of stream shuffling. That's all great, but the new features it allows are really awesome.

Testing is not fully done, but it should be able to understand the two new level formats (MapTemp/MapHead and MapTemp/MapTHead) and bitmap tile sheet graphics. I have confirmed that Bio Menace is fully supported! Abiathar is able to load its levels, graphics, and tileinfo; modify the resources like it could Keen; and save it - the game will use it! Now, I just need to implement Infoplane Override, test more things, and Abiathar v1.5 is ready!
