Right, I've stubbed out FcDirCacheCreateUUID to do nothing and updated
the docs in 'v2' of this patch. Thanks for this preliminary review.

We might consider creating a new element that resets the directory list

        <reset-dirs/>
        <dir>~/.fonts</dir>

would remove all system-specified font directories and add ~/.fonts.
