Providing a already made version

Inside the BloodBathserverjar folder is a already made version of the
code with a .bat file for windows and a .sh for linux and a .command for
mac to use to boot up the jar as a executable. The jar does boot up and
automaticly creates a server.properties file in the same dir but does
not recreate it if one already exists. However the program seems to hang
on server.accept(); and i dont know why.
