cmake-gui: Add option to specify generator toolset

The -T parameter to CMake may now be specified through cmake-gui via a
new text field in the first-time configure wizard (below the generator
chooser).

The generator factories specify whether or not they support toolsets.
This information is propagated to the Qt code and used to determine if
the selected generator should also display the optional Toolset widgets.
