wistumbler2 in two packages: wistumbler2, with console support only,
and wistumbler2-gtk, with GTK2 and console support. This provides a
choice for users of binary packages and lets us catch build problems
in both cases during bulk builds.
While here, fix several issues:
- In the GTK case, depend on pkg-config, needed during the build.
- Patch files during pre-configure, not post-patch.
- Fix the CONF_FILES stuff; it was pointing to non-existent files.
- Reword DESCR.
Because of these changes, that affect the binary package, bump the revision
of wistumbler2 to 1, thus resulting in 2.00pre9nb1. The new wistumbler2-gtk
package is at version 2.00pre9.
