Gui updated, many keyset changes

Gui updated, many keyset changes

I've updated the GUI with an additional window to hold yet more tabs.
This frees up some space on the main window, which was getting crowded with
too many tabs.  I still want to tweak the UI some more, though...

In the process of adding some Pioneer keysets, I ended up totally revamping
the underlying key structure; Pioneer does some rather nasty things to the
standard NEC protocol. :(  I think I now have a better basis for future
keyset additions, but there is much more clean up work left to do...

Yet another attempt to force the package manager to actually manage my files;
I've made a trivial change to the pierogi.sudoers file, hoping that will
convince the package manager to install the dang file if it isn't there.
I'm really getting tired of the Debian system at this point.  (Then again,
I'm working off the Qt SDK here, and their interaction with Debian could be
at fault.)

In any case, yet another massive update.
