Fixed mac build: std::cin::clear accepts one argument
Provide OSXVersionInfo(...) method to retrieve Mac OS X versions in a number format; Update the documentation and add 'Maverick' into OsDisplayString()
Removed MakeFontsLargerOnOSX(QWidget*) font hack for OS X, but retain setting the Qt::WA_LayoutUsesWidgetRect attribute on all widgets
RenderWindow::Resize: Skip checking of equal width and height with renderWindow's width and height in Maverick, as that will always hit for some reason and the 'MainWindow RTT' texture will not be resized
