	<rdar://problem/3758033> REGRESSION (Mail): Support attributes in marked text (International input)

	* WebCoreSupport.subproj/WebTextRenderer.m:
        (-[WebTextRenderer drawLineForCharacters:yOffset:width:color:thickness:]): Changed to support
	underline thickness. Also added a bit of a hack here to move thickness 2 underlines down by
	.5 pixels, since the rendering engine can't give a fractional pixel offset.
        * WebView.subproj/WebHTMLView.m:
        (-[WebHTMLView validAttributesForMarkedText]): Support underline, underline color and marked
	clause attributes. Others that NSText supports are unimplemented for now.
        (-[WebHTMLView firstRectForCharacterRange:]): Remove needless logging.
        (-[WebHTMLView unmarkText]): Updated for new WebCore SPI.
        (-[WebHTMLView _extractAttributes:ranges:fromAttributedString:]): New method to pull the attributes
	and ranges out of an attributed string.
        (-[WebHTMLView setMarkedText:selectedRange:]): Extract attributes and pass to WebCore.
        (-[WebHTMLView insertText:]): Add comment noting that we don't really handle attributed strings
	here.
