remove the custom udp provider

This makes socks-rtc use the UDP provider in freedom-for-chome. Also update to 0.1.4 of freedom-for-chrome which has the recent getInfo fix and test:

npm also seemed to no longer like the version of grunt-typescript we were specifiying...the new version here seems to work just fine.
