4.0.0

#176 Removed the need to manually include the Google recaptcha <script> tag.

This also fixed #175 which was happening to many users if they loaded Google's recaptcha before the angular-recaptcha module.

Upgrade Instructions

Remove the <script> tag that loads Google recaptcha API. You only need to include angular-recaptcha and it will download Google's api only when needed.

Thanks to @felixmosh for it!
