qtevent: Using Signals for Event Handling

So it looks like Qt4 doesn't use signals for event handling. However, due to the nature of C++, it's trivial to extend the built-in widgets, which I did with this. To build, run qmake -project && qmake && make. Here's some sample output from a session:

% ./qtevent

`-> Captured: enter
ls -la $HOME

It makes programming similar to how I did my earlier launcher easier.
