Reformatted maps/*.[ch] with astyle.
Got rid of those annoying spaces between function names and the open parenthases.
More conversions for town1 into Tiled .tmx format.
Converted .pcx images into .png so Tiled can read them.
Created a maps/rules.txt file to define rules for trees (rule1_trees.tmx).
TODO: We still need shadows, which are in Misc.png. Those need to be broken into a different imagemap so we can import them into Tiled.
