	- fixed 3124837 -- Crash trying to handle weird javascript URL in page address field

        * Misc.subproj/WebNSURLExtras.h: Added _web_scriptIfJavaScriptURL for both NSURL and NSString,
	and _web_stringByReplacingValidPercentEscapes.
        * Misc.subproj/WebNSURLExtras.m:
        (-[NSURL _web_scriptIfJavaScriptURL]): Added. Call the NSString version on our absoluteString.
        (isHexDigit): Added.
        (hexDigitValue): Added.
        (-[NSString _web_stringByReplacingValidPercentEscapes]): Added. Converts the sequences into
	character, and then re-encodes as UTF-8. Added a FIXME about doing even better.
        (-[NSString _web_scriptIfJavaScriptURL]): Check for a javascript: prefix, then turn the suffix
	into a script by replacing percent escapes.

        * kwq/KWQWidget.mm:
        (QWidget::~QWidget): Don't worry about the outer view here, since we can never hit one of those.
	Just pass the view to KWQKHTMLPart::widgetWillReleaseView.
        (QWidget::getOuterView): Re-add the assertion I had removed.

        * kwq/KWQKURL.mm: (KURL::decode_string): Made this function return the URL still encoded
	rather than a null string (actually, crashing) when CFURLCreateStringByReplacingPercentEscapes
	rejects the passed-in string. Also updated the FIXME.
        (appendEscapingBadChars): Fixed problem with high-bit-set characters.
        * kwq/KWQString.mm: (QString::setBufferFromCFString): Made this tolerant of NULL.

        (-[WebBaseNetscapePluginView loadRequest:inTarget:withNotifyData:]):
	Use the new _web_scriptIfJavaScriptURL to simplify the check for JavaScript URLs,
	and to use a more tolerant unescaper.
