Add a CairoScript interpreter library and use it to replay the test output for the CairoScript backend. The library is also used by the currently standalone Sphinx debugger [git://anongit.freedesktop.org/~ickle/sphinx]. The syntax/operator semantics are not yet finalized, but are expected to mature before the next stable release.
