deleting gqview and gqview-devel

[Greg Troxel <gdt%ir.bbn.com@localhost>]

gqview ended up with no upstream maintainer, and people in the gqview
community created a fork geeqie, which is, aside from the perceived
necessity of the name change, simply the next version of geeqie.

So I'd like to delete gqview and gqview-devel.

Please speak up with any objections (and a corresponding offer to become
MAINTAINER :-).
