v0.7.1

• added purge_blacklist feature to the g10k config to remove unnecessary files from the sync / Puppetservers, see README.md for examples
• added -environment parameter that uses the source name as a prefix to discern between syncing distinct sources with the same branch name, see #132
• really respect maxworker parameter during git clone/remote update, fixes #140 (#141) Thanks to @maxenced
• added .g10k-deploy.json similar to the r10k deploy result file. This saves a hash sum of the current Puppetfile to detect Puppetfile changes and thus can prevent unnecessary Puppetfile syncs, see #138
