[mkgmap-dev] [PATCH v1] - Code around highway shield crap when sorting labels

This patch codes around the problems introduced by highway shields with regard to the sorted roads: 1 - the sort order should now be much improved 2 - no duplicate symbols (shield version + non-shield version) It also includes a fix to the label reading code so that labels with a highway shield prefix are read in correctly when generating the MDR file. For me, in mapsource, road search for roads with highway shields now works apart from motorways which don't seem to searchable - perhaps that's deliberate on Garmin's part? All feedback appreciated.
