Improve our usage of GRPC proto files

[jamaljsr]

The app currently requires proto to be pre-compiled. This compilation process generates TS/JS code that is not valid and needs some tweaking. I currently do this manually, but it should be automated.

Changes:

• add var proto = { lnrpc: {} }; to the top of lnd_pb.js
• add var proto = { looprpc: {} }; to the top of loop_pb.js
• add var proto = { google: { api: {} } }; to the top of annotation_pb.js
• add var proto = { google: { api: {} } }; to the top of http_pb.js

Alternatively, I would like to do some further research into protobufjs to see if our usage of proto files can be improved even further.
