Update to EnkoderTags Radiant Extension

I’ve updated EnkoderTags to allow HTML attributes in the enkode_mailto tag. The attributes will get passed through untouched into the resulting markup, so you can add CSS classes or IDs to use as styling hooks. For example, this code

<r:enkode_mailto email="example@example.com" link_text="simple email example"

will produce the HTML

<a href="mailto:example@example.com" class="enkodedlink">simple email example</a>

which will be obfuscated through the Enkoder as usual. Thanks to Nick Calladine for prompting me to add this feature!
