Added some traffic signals, bus stops, rail crossings and a few other features in West Perth, Western Australia.

Car Parking seems to be the next logical addition. I will add these as polygons -- thus making it clear how much space they really take up! There is a fair amount of private parking and fee parking in West Perth. Looks like this is the scheme to use along with key=fee.
