Add GNURadio to this tap?

[shafdog]

The GNURadio package/recipe in the core Brew doesn't include QT support. GNURadio has a GUI builder tool that let you build controls to use a software defined radio (SDR) called gnuradio-companion. But the recipe in the mainline brew doesn't build with QT, likely since as best I can tell GNURadio doesn't work with Qt5. Without QT, many examples don't work and the WX widgets are more limited than QT ones in GNURadio. So while the homebrew-core version does "works", it's improvised since apparently GNURadio can't easily be adapted to Qt5.

The GNURadio team recommends MacPorts since it works with all features, but really don't want replace brew and certainly don't want multiple package managers on my Mac. Anyway, found this tap, created a new version of the gnuradio.rb recipe that uses this QT tap & enables QT build option... Seems to build/work, at least for me.

Not sure if it belong here or not, but since it did take quite a bit to figure out...below the alternative gnuradio recipe I used with this tap to get QT working in gnuradio-companion.

Anyway, this works for me:

I'd be happy to include this formula in my tap. Could you please submit a pull request with it?
