Please change the name and repository location of CL-TEST-MORE

[fukamachi]

I renamed CL-TEST-MORE to prove.

The new repository location, that the old one redirects to, is here.
https://github.com/fukamachi/prove

Many, many projects depend on cl-test-more (under that name). Removing cl-test-more will cause a problem for a while. Does it work to have both projects in Quicklisp for now?

[fukamachi]

As prove also provides 'cl-test-more.asd', it won't give serious damage to projects using cl-test-more, I think. (it will?)

Ok, great!
