Mike Frawley b5449ca89a Add rake task to build with closure advanced optimizations.
You would use this to compile your code _with_ underscore, to
remove all those dead underscore functions you don't use.

Slight tweak to code to `root._` code to get working, and must
remove anonymous wrapper function for current closure compiler to
remove dead code.
