WebCore:

Reviewed by Darin, Maciej.

Removed many uses of NSString *.
Moved a few methods from WebCoreFrameBridge to FrameLoader, replacing
stringByCollapsingNonPrintingCharacters with a c++ equivalent.

PLT says no performance regression.

WebKit:

Reviewed by Darin, Maciej.

Removed many uses of NSString * from WebCore.

Changed a few files to ObjC++ for compatiblity with new WebCore methods
taking WebCore::Strings as arguments.

Added a static_cast to make the c++ compiler happy.
