Windows version runs now

There are a number of bugs that (being present in, at the very least,
wine) I have yet to address, such as:
 * There is no keyboard input
 * There is no mouse input
 * Checking if the window is closed does not work
 * Color filling GUIs do not work, and, as far as I can tell, neither
   does object storage
 * There seems to be some kind of bug introducing garbage data in
   asset.c
