* Previous "virtual" classes (which can't be instantiated) are not corretly named "abstract". * Added a new "virtual" category for classes, they can't be instantiated from the editor, but can be inherited from script and extensions. * Converted a large amount of classes from "abstract" to "virtual" where it makes sense. Most classes that make sense have been converted. Missing: * Physics servers * VideoStream * Script* classes. which will go in a separate PR due to the complexity involved.

Range is a base class for [Control] nodes that change a floating-point [i]value[/i] between a [i]minimum[/i] and a [i]maximum[/i], using [i]step[/i] and [i]page[/i], for example a [ScrollBar].
