- cover zero area intersections, treating them like empty - cover heterogeneous intersections, removing zero area shapes - cover invalid paths on the input or output side (from rounding) via repeated simplification - cover invalid paths which cannot be repaired through simplification directly (find a new starting point in the point sequence) - update shapely

@finkf I won't be revisiting the h/v-line detection any time soon, so I bundled that tiny change with a number of fixes improving robustness (parallel to our current problems with Shapely in other modules). In anticipation of your approval, I increased the version number once again. When we merge, we should avoid squashing. |

Fix #59
@finkf please don't merge yet! I'll try to aggregate more useful fixes for h/v-line detection here (which is crucial for segmentation, but still has lots of potential when compared with the recipes in Tesseract). Also, this can serve as a testbed for others for the time being.
