updating release script and Gruntfile to push to different places on

@willscott 
Does this new directory structure make sense to you?
see freedomjs.github.io repo for what the new dist/ folder looks like
I'm not as concerned with this task not running in windows, but more just wanting a sanity check that it doesn't cause the whole gruntfile to not load in windows. Bonnie / Liz were using windows without cygwin this summer, and were able to do the compilation & unit testing, iirc.
