JOPL adlib livecoding environment; stop including JIM files in git

I now have multiple executables that depend on the same .jor source files
and I am not diligent about ensuring that both are up-to-date and working.
As small changes to source files can cause .jim files to fail silently,
I've removed them from the repo for now.
