#347 Add mode for clojurescript

[J David Eisenberg]

Here is a patch for adding ClojureScript mode to jEdit. Since Clojure and ClojureScript use the same syntax, no new XML file should be needed, though I add it as a separate MODE in case there is a divergence that requires a different XML file.

Note: this is very low priority (I presumed 1 is lowest, 9 is highest)
