Fixes

So I got around to do this: Tests are properly loaded and executed via ASDF (whether or not the pattern is the best is debatable), i.e. I added `:IN-ORDER-TO` to the ASDF systems and RT is replaced with an ASDF dependency, e.g. http://git.b9.com/rt.git or from Quicklisp. Also there were absolute pathnames in the tests, so I switched that with the ASDF relative pathnames.
