added functions to mess with the "return to" stub. everything should be working right, but if i messed up, it may cause you not to be able to exit the program (it could just keep restarting itself). now when booting homebrew, they should exit back to this program if you have a channel installed as UNEO or ULNR. priority is given to UNEO if both are present.
