BadChar character class. This causes them to remain unescaped
	in KURL objects. As a result, some extra escaping needed to
	be added into the getNSURL() function to enable NSURL
	objects to be created using a KURL.

	This enables me to fix this bug:
	Radar 3050437 (Clicking link leads to page with garbled content)

	Note, however, that my fix for 3050437 relies on this bug remaining unfixed:

	Radar 3102332 (Square bracket characters "sneak through" CFURL illegal character checks)

        * kwq/KWQKURL.mm:
        (KURL::getNSURL)
