Create new layer for "ref" of minor roads and paths (#3709)

* Move residential, unclassified and track "ref" to new layer later in project.mml * Change residential/unclassified ref to same size as name at >z17: This makes the ref lables at z17 and up consistent between track roads, paths, residential and unclassified highways * Change unclassified and residential text ref halo-radius to standard size * Change unclassified and residential text ref to oblique (italic) font
