Map Editor can now PLACE tiles :)

The map editor can now place tiles, of course its very limited at the moment. I still need to make basic tools to make tiling easier, such as a fill tool, rectangle fill, etc.

I'll probably omit the filename text in the corner for some basic brush types to select such as those said above.

All thats left after that is moving the view position (to make the map bigger than one screen) and saving/loading system.
