add "dependencies" and "test" to "make all"

make all does build the game, and another few things which are required for that. This should be "make game" but we named it "make all" so we should also copy the dependecies (before compiling) and test also the compilation. In this case when we checkout a branch all should be okay. but sometimes it isnt. so we should make a "test" after building the project to ensure that all is good and is as it should be.

i can only change / test it under Windows :( can anyone test and change the linux "makefile" version?
