Fix for issue #7458: View doesn't scroll down after Edit > Move Line Down
Added ClojureScript and cljx extensions to clojure fileExtensions

[ClojureScript](https://github.com/clojure/clojurescript/) is a Clojure implementation targeting JavaScript. [cljx](https://github.com/lynaghk/cljx) helps write Clojure/ClojureScript portable projects.
Both are very common and should probably be recognized out-of-the-box by Brackets.
