smackdown 6.x-1.x-dev

This is a slimmed down version of the 5.x-dev.

CHANGES
We do not implement our own content type, voting widget, or taxonomy narrowing of what goes into our nodereferences. Instead, our content type is preconfigured and stored in a new file (smackdown.content.inc) which is imported upon installation. This allows us to remove our custom table and autocomplete fields, replacing them with a core node content type and CCK nodereferences which can be configured by the user. This also allows the pairing (comparison) of two different types of content types. The voting widget is replaced by some javascript detecting our node reference links. So if it's not a link, it won't work. See the selectors in smackdown.js for specificity.
