Behind raw_input

This was a pretty heavy week.

there were two ways of approaching the raw_input problem, the right one, and the wrong one(lol):

• To fill the widget definition with signals and slots which will communicate the different IOs to the mainwindow and this one then will communicate those IOs to the kernel.
• To import zmq in the ipqt_popup module and manage the communication directly with the kernel.

I innocently chose the fist one (FAIL), "entia non sunt multiplicanda praeter necessitatem".

The widget was almost done when Fernando corrected me the design stating that it will be better to print all the messages from raw_input or pdb in the mainwidow not in a popped up widget.

Fortunately I managed to understand the mechanisms required for this to work correctly and I'm finishing it right now.
