Lots of further modifications, once again, mostly clean-up. Most of this is prepping for my big change to this dialog, to add some shnaziness to the code, it was pretty messy, and should be considered necessary, we -want- to have clean/pretty code. I may still have more to go :P .

* Added QCheckBox in _p.h

* Removed the above's forward-declaration, since I need to access it directly in this header

* Removed #include <QCheckBox> in .cpp file, it's declared in private header now.

* Renamed -multiple- slots that used _k_ type of function names, to something more intelligible.

* There was a bool keepOpenChecked, this was worthless, it was _actually_ being set when the checkbox was triggered, and was used later on... but we had a pointer to the checkbox... we could have just asked it for ->isChecked();

* Also removed method keepOpen, which returned a bool value of that only.

All kinds of good cleanup changes that had to be done, and I wanted to split this from my other overhaul, since that could get big also...especially if someone wants to revert just one part of it, etc.
