fix reloading of clj files in cljs dirs

cljsbuild “auto” produces different results than “once” if a clj file that is a dependency of a clj based macro file changes.  This is because non-macro clj files are not reloaded on change.

This issue https://github.com/emezeske/lein-cljsbuild/issues/210 is why a guard was put in to prevent the loading of non macro clj files.  This issue appears to have been resolved as of clojurescript 2202.

And so I removed the guard that only allows .clj files that contain macros to be reloaded.  I have tested this and it works pretty darn good :)
