templater: add inheritance support to style maps We can now specify a base map file: __base__ = path/to/map/file That map file will be read and used to populate unset elements of the current map. Unlike using %include, elements in the inherited class will be read relative to that path. This makes it much easier to make custom local tweaks to a style.
