Fix "strategies" accounting for 0-length linestrings and degenerate polygons (#137)

Browse Source 
* Dropping a 0-length feature doesn't count as dropping-as-needed

* Add an option not to reduce tiny polygons to dust at maxzoom

* Add test for prevention of tiny polygon reduction at maxzoom

* Fix accounting for tiny polygons not to include degenerate geometries

* Revert "Add test for prevention of tiny polygon reduction at maxzoom"

This reverts commit f931bbd73e.

* Revert "Add an option not to reduce tiny polygons to dust at maxzoom"

This reverts commit 03f0882bb6.

* Fix tests

* Another test that no longer has any really tiny polygons

* Oops, that broke LineString simplification

* This time for sure!

* Update changelog and version
