Title: Improve email sharing

* Users have to enter the security code in a captcha image before
sending out the sharing email; added security measure. The captcha is served via the `captcha` module - https://github.com/ekala/kohana-captcha

* The email body is no longer free text and has been replaced with a
standard message

* For limiting the no. of emails that a user can send, we'll probably have to extend this functionality to include tracking the no. of times an item is shared across the various networks?
