dexconf to use debconf db to add xfs-xtt entry in font-path

[wilfried Goesgens <willi@almado.de>]

Hy, basing on the stuff I found out about debconf, dexconf, and the
entries xfs_xtt makes in the debian config database I've patched dexconf
to add a FontPath entry to the X-configuration if it finds xfs-xtt.
I don't know if I found all points regarding the db_get stuff, please
correct me if i'm wrong here.
