- Removed double quotes from the "OPENVPN_OPTS=" line due to literal interpretation that would cause an issue at /openvpn/start.sh:57 when executed.
- Fixed failing "proxy/build" instruction. Splitting into "context" and "dockerfile" subkeys prevents the error "TypeError: You must specify a directory to build in path"
- Introduced "image: haugene/rpi-transmission-openvpn*" lines to each docker-compose structure to transition to Docker Hub hosted images in the future. (see https://resin.io/blog/building-arm-containers-on-any-x86-machine-even-dockerhub/)
