(svn r15340) -Fix [FS#2121]: changing town road layout in-game caused ugly road networks

Browse Source 
-Fix: use a flag instead of TL_NO_ROADS to forbid towns to build roads. The flag is ignored during world generation, so there won't be 'ghost' towns anymore
-Feature: town layout is now stored per town, so it is possible to (manually) set different layout for each town
