        - renamed DOMString and DOMStringImpl to String and StringImpl, and moved into platform

        * config.h: Put in transitional defines so old code can still refer to the classes
        as DOMString and DOMStringImpl.

        * platform/AtomicString.cpp: Added.
        * platform/AtomicString.h: Added.
        * platform/AtomicStringImpl.h: Added.
        * platform/PlatformString.h: Added.
        * platform/String.cpp: Added.
        * platform/StringImpl.cpp: Added.
        * platform/StringImpl.h: Added.
        Moved files here and renamed them. PlatformString.h would be named String.h except
        that conflicts with <string.h> on non-case-sensitive file systems.

        * khtml/xml/dom_atomicstring.cpp: Removed.
        * khtml/xml/dom_atomicstring.h: Removed.
        * khtml/xml/dom_stringimpl.cpp: Removed.
        * khtml/xml/dom_stringimpl.h: Removed.
