Patch by Zan Dobersek <zdobersek@igalia.com> on 2013-10-28
Reviewed by Darin Adler.

Make the constructors of the InputType subclasses public. This makes it possible to use std::make_unique on these classes
and makes the T::create() helpers redundant. New instances of these classes are now managed through std::unique_ptr.

InputType::create() now uses a NeverDestroyed InputTypeFactoryMap that maps type names to InputTypeFactoryFunctions and
gets populated when the method is first called and the map is still empty. Certain types are not added to the factory map
if they're disabled at runtime.

The factory is used to create the new InputType object if the requested type was found in the map, and TextInputType is used otherwise.
