ipc

add ipc functionality so it's possible while the program runs to:

~~play next and previous track with cimp --next and cimp --prev~~
~~change volume with cimp --volume xx~~
~~add file to playlist with cimp --add filename.ext~~
if started without --add it should clear the playlist and load and play the given file or playlist.
if given the flag --playlist it should output the song array as a playlist.
start stop pause and quit would be good, repeat as well. the c functions are ready in terminkey.h and an example of how it works is found in test_ipc.bas
