just resize default window on desktop project (800x600)
refractor on static Textures
make Case system serializable (Java serialization, not GDX serialization).
It seems it's work on desktop project, buf it's not tested with Android systems.
Maybe I have to switch with Gdx serialization, wich use JSon format.
add load and save system using serialization
For load, just read the serializable object into the file, pointed by the name of the Lvl.
For example, if the parameter equal "myLvl", load try to create a Map to read the file at "./data/lvl/myLvl.fem"

save method (using for editor) check the first line/column, and the last line/column (i.e. the first/last which no "NOTHING" Case) and save the rectangle finded. So, the map can't begin or end by an "NOTHING" case
Warning: cases inside the rectangle map isn't checked, but put a "NOTHING" case is absolutely forbidden when you load the map for playing!
just remove file extension, already put by the save method
Map Editor now use a listener and the GraphicMap for draw genericaly
add Map Editor Listener's used for change cases on MapEditor system
add external datas (images, level ...) to the project
