Miscellaneous fixes

1) 'prod' mode now works.  This can be achieved by running a 'grunt -f' in the client folder which will perform a variety of code optimizations (not performed when running a 'grunt serve' and copy these optimized items to dist/ in the server folder.  Now in the server folder we can now run 'npm start' .  This will tell the server to look in the new dist/ folder rather than back at the client folder (which is done when 'npm test' is running).  This mode this is the mode we will use when deploying the app and probably when we demo it.

*<b> you need to do a npm install in the client folder after pulling this<b>*
