Updated VEGAS protobuf.  Multi-connections. Check active banks.
Make libraries local, test missing freq info.

The external libraries (e.g. jquery) need to be hosted
locally because machines in the control room have limited
exposure to the web.

I also added code to check for LO/IF frequency infomation
before attempting to use it.
