1.0 Compatibility

Leaflet 1.0 changed the way L.TileLayer and other tile related functionality worked, which means that the master branch is not compatible with Leaflet 1.0. The 1.0dev branch has been setup to get leaflet-tilefilter working with Leaflet 1.0. Currently, all features work, but there are some issues with tile refreshing, general interactivity that need to be addressed.
