Filelist

Add an option to the jshint task to control the way rhino is called with the filenames of js files to be checked. Add a parameter to jshint-rhino to read filenames from a file instead of from command line.

This is to solve command line being too long when running on Windows. With the option enabled, the filenames are stored in a text file, which is given to jshint rhino with the new -f flag.
