Add Stack viewer.

As outlined in this task.

#127

Address:
SS is the stack segment.
In x86 real mode which is the legacy mode in which all PCs boot, memory is accessed using a pair of registers, and for stack it is SS:SP.
Effective physical address computation is SS*16+SP. More info here: https://en.wikipedia.org/wiki/Real_mode

Content:
x86 stack can contain 16, 32 or 64 bits values (yay!). There is no good way of representing that.
What would be useful would maybe to have a table that would display a column for each 2 bytes address in rows and with various visualizations in columns so that different representations could be seen for each address.

I've noticed detached windows are always been detached as minimized windows. I need to look into this.

Some info:

Assuming your widget is w, then try

w->setWindowState(w->windowState() & ~Qt::WindowMinimized | Qt::WindowActive);
to restore the window, and

w->setWindowState(w->windowState() | Qt::WindowMinimized)
to show the window minimised.

For the stack viewer, it looks like this:
