Use sign formspec to switch between wide/narrow font

if available on a given sign. The sign must have a "foo:bar_widefont" variant, with the horizontal scaling set appropriately (about half of the normal value for the narrow-font sign) Add new corresponding API to anto-generate those signs where desired; use this feature in default wood and steel signs
