* Production: Multi-stage Dockerfile.
 * Production: Adds VERSION ARG to specify the lbrynet version to download.
 * Compiler: Adds REPO ARG to specify alternate git repository to build from.
 * Fixes checkmount arg passing.
 * Adds correct binding IP address to start.sh
 * Adds mountable config to start.sh
 * Does not yet add any Layered Config like #70 (it's harder 'cause yaml)
