[hpsdr] Updated KISS Konsole for Cross-platform Execution

[Jae Stutzman]

First let me say, this is good progression in a short period of time. I
like that there is demand for this type of work among the community. I also
agree with John about native UI toolkit (or at least more native). I don't
know much about Ximian.Forms except that it is a proprietary extension to
Mono for use on mobile devices and is behind a payment subscription (I
would not recommend its use here).

I do have experience with GTK# (which is what monodevelop is written with).
It looks mostly native on a lot of platforms, including the 3 we've been
discussing: Windows, Linux and Mac. Monodevelop has a good UI designer that
works on all platforms, so it is fairly trivial to whip up quick UI
prototypes. GTK# is a fairly thin wrapper around the GTK+ c library, which
is a high performance gui framework.

I've been toying with the idea of jumping into a UI port with KK using GTK#
(a bit excited actually). A port to GTK# would bypass the Jetson WinForms
issue we stumbled on earlier last week.

There are c# language bindings for QT, but they don't appear to be as
popular or as maintained. However, there may some ability to reuse other QT
gui work if it is used.

I'm all for more UI abstraction as well.
