Flag to reduce precision of GeometryField

DRF 3.8 support

Fix default widget for GeometryFilter

Using `forms.BaseGeometryWidget` will cause a IsADirectoryError, because
of an empty template_name being used.
This was added by me in eb54fc06.

This patch changes it to use a simple TextInput; I can imagine using a
nicer widget here, but that requires to also add/handle the required
media assets, which was not trivial (IIRC).
