Make Keymatches Templated / Easily Themable

The Appliance itself is very limited in what it's able to return on a keymatch: a title field and a URL field.

What is very common practice is for the title field to be overloaded with pipe-delimited information. In this way, it's possible to theme in something richer than just title text and a link.

There are some limitations: the GSA Admin configuration page is limited to 100 characters in the title field, and the maximum size of the field in general is something like 256-512 characters (which can be achieved by circumventing the first limitation by adding keymatches via a spreadsheet).

Rather than supporting a number of fields with pipe delimited information, it might be better to implement a special content type that contains an arbitrary collection of fields. Then, the title entered into the GSA configuration for keymatches would be something like...

KeyMatch Title|nid

Where 'nid' is the Node ID of the corresponding keymatch content. We'd load the node based on the nid that's passed through (or just default to current behavior if no nid is found in the title string), and then pass the node object to a theme function or template where the fields can be themed into something appropriate.

Don't know if this is appropriate for the core Google Appliance module or better off as its own thing.
