Minimum node gypsy file required for working compile (for me)

After a comment from @tlbtlbtlb I reviewed the gypsy settings, and pared them down to the minimum it took for me to make a working compile on my system. Hopefully it's the same for others! 

Like I said in the initial PR, I'm not a C++/Xcode pro, so keeping things simple seems like a smarter strategy for me. :)

I'll try to get a simple grunt-based test in a future PR. Had a bit of a time recreating one.
