- removed use of DeprecatedString for font family names

        * css/CSSFontSelector.cpp:
        (WebCore::CSSFontSelector::addFontFaceRule): Update for name change.
        * css/CSSParser.cpp:
        (WebCore::CSSParser::parseFontFamily): Update to use new appendSpaceSeparated
        function and String rather than DeprecatedString.
        * css/CSSStyleSelector.cpp:
        (WebCore::CSSStyleSelector::applyProperty): Updated for name change.
        * css/FontFamilyValue.cpp:
        (WebCore::FontFamilyValue::FontFamilyValue): Replaced code using a regular
        expression with code that does the same thing more efficiently.
        (WebCore::FontFamilyValue::appendSpaceSeparated): Added.
        (WebCore::FontFamilyValue::cssText): Updated for name change.
        * css/FontFamilyValue.h: Changed DeprecatedString to String. Renamed fontName
        to familyName and parsedFontName to m_familyName. Removed unused genericFamilyType
        and m_genericFamilyType. Added appendSpaceSeparated so that m_familyName can
        be private instead of public.
