Dep bump and alphabetizing dep  fix: #464

Alphabetizing and bumping outdated dependencies.  I think this will fix #464 as `forever-monitor` has node dependency to 0.8.x where as the latest forever-monitor will take anything greater than that so it should work.

upgraded:
forever-monitor ~1.1.0 to ~1.5.2
supertest	~0.10.0 to ~0.15.0 // despite the comment in gruntfile.js it seems to be working and test passes.
grunt-contrib-imagemin ~0.3.0 to ~0.9.2


Also, is it correct that we are keeping socket.io where it is because phantomjs doesn't work with the newer version of socket.io?  Couldn't get click test to pass after bringing socket.io to latest
