Replace template function with template class to placate VC6.

Browse Source 
VC6 has very poor support for template functions and in particular doesn't
understand explicitly choosing the type of the function to call so replace
template DoApplyToFont() function with FontModifier template class in
wxMarkupParserAttrOutput implementation.
