Added layout.dtd file for formatting. This includes elements for page layout, system layout, staff layout, measure layout, and scaling from tenths of staff space to millimeters.
Added to10.xsl file for transforming a MusicXML 1.1 file to a MusicXML 1.0 file. Removed the to06c.xsl file.

Added defaults element, including default layout, fonts, and lyric languages.
Added credit element for title, composer, and other credits that appear on the first page of a score.
Added scaling, page-layout, system-layout, staff-layout, and measure-layout elements in new layout.dtd file.
Added barre element.
Added harp-pedals element.
Added scordatura element.

Added print-style entity, grouping together entities for position, font, and color.
Added width attribute to the measure element.
