Fixed issue of not showing, due the wrong protocol use, 
A site working on SSL will not accept including and loading a js file over http (insecure)
So I made changes to the recaptcha_get_html() function and let wordpress decide is_ssl() to use wich protocol.
insteed of setting default on insecure http. and in the import script lines I have changed http in https.. you always can load a https into http..
Checked it in a dev envirorment and a live one..
wp-recaptcha-integration ssl fix, changed the recaptcha_get_html function, so wordpress core function is_ssl() will check if ssl is needed or not. And changed the http to the https protocol for including the recaptcha api, https wil give an security warning and wil not allow you to add a remote js file using the http link..while http will accept https...
Merge origin/ssl-fix into ssl-fix
