Move the executable to runtime dir

Since the executable file seems to need to have files in the same
directory it is in, I need to move it (hopefully only temporarily).
This still isn't perfect, because the program needs to write to the
runtime files, which thus need be moved to somewhere writable: temp or
home.
Change it to run from home dir

Change the wrapper script to execute program in runtime directory in
home directory, and add a note for user that files need to be copied to
home.
Works alright finally, although damn ugly.
