Replace simple.css submodule by release copy

This is way simpler to handle since you can get a full tarball of Ceres
with everything included which is necessary to run it.

The LICENSE of simple.css allows such a copy and stays inside the copy
to make clear that this folder uses the simple.css license and not the
one of Ceres.
