Feature: decorate tile urls with query params

[mikey75]

Some online tile services require api keys or other parameters in the tile url request. Perhaps it would be nice to allow AbstractTileFactory to decorate urls/request with such parameters? It could be doable by passing map of key/value pairs to factory.
Of course it is a convenience feature because you can implement it in your factory yourself, but would be nice to have in superclass and just set the parameter map.

I will try and implement it but what do you think?

That's an interesting idea. Yeah sure, let's give it a try. Maybe a separate helper class that creates URLs that can be used in a superclass could be useful.
