amaze.autotag.v1

NOTES: Re-work of initial autotag.js supplied by Adam.G
Constructed using javascript object literal notation, http://www.dustindiaz.com/json-for-the-masses/

TODO: Very much a beta, needs a bit more thought about structure and the options override.
Should we be able to turn certain events on/off...?
Look at adding in RSS event tracking but we need a standard way of pinpointing RSS links.
You could add a class="rss" to each link or make sure you output a <link /> in the head which would then reference the link on the page.
For example: <link rel="alternate" type="application/rss+xml" title="RSS" href="url/to/rss/file" />
