Added knowledge of virtual size to wx(Scrolled)Windows, they can now

manage their own scrollbars with the help of a sizer or other user
clues (SetVirtualSizeHints) without the need for an ancillary container.
Added SetSizerAndFit convenience method.
SetSizer now enables/disables AutoLayout automagically.
Logic bugfix for scrollsub sample.
Syntax bugfix in parser.y.
Compiler warning fix in textctrl.cpp.
