Parse new fonts.xml config file, and resolve weight selection based on the base weight of the font (as defined by a weight alias specified in the config file) and the requested bold flag. This change improves the appearance of bold spans for alternate weights of Roboto. In addition, this patch enables weight selection for fallback fonts. For example, if an additional font with a weight of 100 is added to the Hebrew font family in the fallback list, then requesting "sans-serif-thin" would select that font for Hebrew text.
