Format Spec v0.05:
Signature (3 ints)
Version (float)
Level Name (string)
Level Width (int) (pixels)
Level Height (int) (pixels)
Level Parallax (float)
Level's Music Index (int)
Level's Background Index (int)
Level's Weather Index (int)
Current Layer (int)
Current Tileset (int)
ScrollX (float)
ScrollY (float)
Editor Mode (int)

For Each Layer...
Layer State (bool)
End For
Number of Tilesets (int)
For Each Tileset...
Tileset's Name (string)
Tileset's Width (int)
Tileset's Height (int)
(the two sizes are for creation of a temp texture in case of failure)
End For
For Each Layer...
For Each Tile That Exists...
Array Position (int) (this will be read as -1 if end of layer)
Tile's X (float)
Tile's Y (float)
Index of Tileset (int)
End For

Number of Entities (int)
For Each Entity...
Entity's name (string)
Entity's width (int)
Entity's height (int)
Entity's x-position (int)
Entity's y-position (int)

For now, that's it.
