(svn r9779) -Feature: Add the possiblity to choose different road patterns for towns to use.
Possible patterns are : No Road (not available in scenario editor) Original (for the nostalgics) Better Roads (same as original, but based on distance of 2 tiles instead of one) 2x2 grids 3x3 grids Patch by skiddl13
