Added bin/beautify_js, which is a wrapper for rhino beautify-cl.js that

also lets you supply input via standard input rather than suppyling a
filename. This allows it to be used in vim as a filter command.

+Using this is a vim filter command
+----------------------------------
+
+This can also be used as a vim filter command (see help filter).
+
+Simply select the lines to be beautified in visual mode and type .!beautify_js.
+
+Better yet, create a vim command to execute it for you, and put that in your .vimrc:
+  command! -range=% -nargs=0 BeautifyJavascript <line1>,<line2>!#{$0}
+
+Then you can simply type BeautifyJavascript to process the entire buffer or select a range of lines to only pass those lines through the filter.
