Common continuous integration scripts for all SCAII environments and libraries

General-purpose protobuf compile scipt for SCAII and Sky-RTS. Requires Python 3

1. Clone SCAII and Sky-RTS repos into desired location
2. Clone this repo (CI) into both SCAII and Sky-RTS
3. Execute this script with command python gen_protos.py
   • In SCAII, this script will find the directory containing scaii.proto, cfg.proto, and viz.proto. It will then output vizProtos.js into SCAII/viz/js and scaii_pb2.py, cfg_pb2.py, viz_pb2.py into SCAII/glue/python/scaii/protos/
   • In Sky_RTS, this script will find the directory containing sky-rts.proto. It will then output sky_rts_pb2.py into Sky-RTS/game_wrapper/python/protos/.
