Now we have a fully working Table Model that updates on demand.

The model now works, and I can see it being updated every request.

The next step is to add aditional information and work on the GUI to make it
look nice. For now it'll be READ-ONLY. A view into rTorrent of sorts.
Update the GUI code to display the new table model

The MainWindow will now display the new table with its information. There's
still a lot of work to do to make this GUI better.
