Placeholder for giongi/gitaigo ("sf/x") searching

I will be converting the giongo/gitaigo data to the new database format for searching, but given that there's still quite a bit of work to be done before we can switch over to this new site as the new nihongoresources website, there's still some time before this will be in.

As such, if you have a good idea of how you would like to search for this data, and how it should be presented, do let me know by visiting the contact page and leaving a comment about this.
