One lane to rule them all!

• bundle exec fastlane release on any branch - that's how simple it is:
  • register specs repo if one isn't yet in your system
  • check if current branch is clean
  • checkout to master and pull any changes
  • update version in podspec, either to one from version argument, or patch update by default
  • commit and push to master with message, either from message argument, or default one
  • create tag either from version argument, or from default patch version update and push it
  • finally, validate and push pod to specs repo

Advanced usage: bundle exec fastlane release version:1.2.3 message:"my new version"
