Allow different query paramter on suggest.js

[yoavf]

The current suggest.js defaults to the "q" parameter for the query string.

This patch allows the user to define another parameter. If no parameter is defined, the script will default to "q".

I would like to see capacity to add additional parameters.

For example if we want to use suggest.js to do auto completed on field in MetaBoxes we'd also need to sent the the nonce field for verification.

Closing since this is really stale. I've personally lost interest, and I don't think there's any interest here.
