deal with filename altering by e.g. django-compressor

[nimasmi]

django-compressor, with the compression option turned on, renames included js files. This means that Leaflet can't use its own filename to determine the path to image files, see https://github.com/Leaflet/Leaflet/blob/5a518194945813f4b578861799f23a94248b553e/src/layer/marker/Icon.Default.js#L23-L25.

This edit adds a settings option SET_IMAGE_PATH_MANUALLY, which will cause the file path to be written manually at the end of the generated js includes:

L.Icon.Default.imagePath = "{% static "leaflet/images" %}";

Thanks for this contribution !

That's something we had done manually before :) See https://github.com/makinacorpus/django-mapentity/blob/master/mapentity/templates/mapentity/base.html#L119

I wonder if the option name is well chosen though. This is not really manual, but rather... automatic! We could call it with something like FORCE_IMAGE_PATH ?

Very happy to agree to a name change.

I would also rephrase that to "Force Leaflet image path"
