/**
* Changes obfuscated email addresses to normal email links.
*
* @name Unobfuscate
* @version 1.0
* @author Bohdan Ganicky
* @requires jQuery http://jquery.com/
* @param atstring String to be changed to '@' sign. (default: '[at-sign]')
* @param dotstring String to be changed to '.' sign. (default: '[dot-sign]')
* @desc Simple jQuery plugin for defuscating obfuscated email
* addresses, changing them to normal 'mailto style' links.
* Good to use when you don't have control over what's coming
* from the server. Accepts various formats including links:
* - <span>bob[at-sign]mail[dot-sign]xy</span>
* - <a href="mailto:bob[at-sign]mail[dot-sign]xy">contact</a>
* - <a href="mailto:bob[at-sign]mail[dot-sign]xy">bob[at-sign]m
* ail[dot-sign]xy</a> etc.
