Refactored GIS-related JavaScript initialization to eliminate inline
scripts from templates. Added support for specifying a base layer using
the new `base_layer_name` attribute on `BaseGeometryWidget`, allowing
custom map tile providers via user-defined JavaScript.
As a result, the `gis/openlayers-osm.html` template was removed.
Thanks Sarah Boyce for reviews.

The eslint configuration and the admin script compress.py have been
updated for ES6.
The unused fallback of globals.django in jquery.init.js was removed. It
is always included before jsi18n-mocks.test.js and it always sets the
global value.
