A few additions to OSM-ISSprOM 2019.crt

[Choreuomai]

This is my first attempt at contributing. Please be patient with me in case I am doing stupid things. Just a few, unsystematic improvements (I hope). Added 501.6 for some tags with highway=path because highway=path is is often used in OSM for paved footways, too. Added 501.8 for similar reasons with highway=track Added 401 for residential=apartments because this tag can be used for apartment-block residential areas, which very often are possible to enter Added 520 for tennis courts because it helps when they stand out from what is usually yellow, you can then still replace with fence manually Added 520 for gardens and flowerbeds
