Split VATES Gui into central Widget and smaller QMainWindow

[Michael Reuter]

The central widget in VsgMainWindow needs to be split out into its own class. This will ease the integration into MantidPlot. The VsgMainWindow can then be condensed into a smaller class that just uses the new central widget class.

After split, most of the functionality is working. However, the time control widget and the pipeline browser widget are non-functional. I will work on this, but other reorganization work will continue at the same time.

The split is complete. The code for VsgMainWindow is now very small since the bulk of the functionality is handled by MdViewerWidget.

Nicely done in VsgMainWidget. Simple Gui works as expected, so refactoring successful.
