Adds a shortcode button to the WordPress TinyMCE editor for easy anti spambot email links.

Adds a button to the TinyMCE editor that puts a selected email address into a shortcode [email] and turns it into a mailto-link, which uses WordPress’ native antispambot() function to encode the emailadress so harvesters can’t get it.
This is my very first public plugin, so please be gentle with your comments 😉
