Added 'test-shortcut' macro for easier testing inside a REPL.

The macro accepts a single regular expression which should match all
relevant test-namespaces. The macro creates a single function (rat)
([r]un [a]ll [t]ests) which runs all tests with the given macro regex.
Further (rat namespace) runs all tests inside the given namespace only.
