Bug#1041791: darkradiant: depends on unmaintained gtkmm2.4, and indirectly on GTK 2

darkradiant Build-Depends on packages from src:gtkmm2.4, a C++ binding
for GTK 2.

GTK 2 was superseded by GTK 3 in 2011 (see
<https://bugs.debian.org/947713>). It has been discontinued by its upstream
developer and no longer receives any upstream maintenance.

>From a quick look at the binary package dependencies and source code,
it looks as though darkradiant is a GTK 3 application already, and the only
reference to gtkmm seems to be in
plugins/dm.objectives/util/TwoColumnTextCombo.h, which is not compiled
when using Debian toolchains, only when using MSVC or Xcode. If that's the
case, then this build-dependency can probably just be dropped.
