Release 0.14.0 (#300)

* Introduce script to automate release

* Rakefile levelup

* Version 0.14.0

* Fix newline at end of podspec.json

* Ensure we start and end on master branch

And that we pull latest master before tagging

* CRLF at EOF

* Remove [:version] param from `release:finish` task

It can be guessed from the current podspec version

* Fix create_release task

* Ensure we run rake via bundle exec
