[mkgmap-dev] [PATCH v1] - make cycleway tracks

As requested, here's an option (--make-cycleway-tracks) to enable the synthesis of cycleways when a (non-cycleway) way is tagged cycleway=track. I have also tweaked the code for making opposite cycleways - it now gives the synthesised way a highway=cycleway tag which it wasn't doing before. So anyone who was using the --make-opposite-cycleways option, please test to see it hasn't been broken. Cheers, Mark
