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.
