Add an option to buffer polygons outward to keep them from collapsing #160

Specifically the files in tests/buffer-polygons would previously collapse away inconsistently from zoom level to zoom level.

Continuous polygons as detected by --no-simplification-of-shared-nodes are unaffected by the new --buffer-polygons-outward flag.
