Orphaning cellwriter

[Jeremy Katz <katzj redhat com>]

Since I'm no longer actively using a tablet, I'm going to orphan
cellwriter (http://risujin.org/cellwriter/).  I may have been the only
person using it, but it's a reasonable app for basic handwriting input
if anyone wants to pick it up.  Upstream was pretty responsive to the
few bugs I found as well.  

If no one responds as being interested in taking it over in a couple of
weeks, I'll block the package from rawhide
