Fix latLng nulls + right click move marker implementation

[RamezIssac]

Fix #55

Plus a new feature:
Ability to change marker position with mouse right-click.

[manosim]

Yes! That fixes issue #55 . 👍

I'm still seeing the "latLng nulls" issue,
is it fixed for you?

[manosim]

Make sure you first uninstall the current version and the reinstall from remote like:

pip uninstall django_geoposition
pip uninstall django-geoposition
pip install git+https://github.com/ekonstantinidis/django-geoposition@5b33eefffe2c65957403aa610bae3c212f404cdf

Can't remember if it's the 1st or the 2nd so just make sure it's removed completely. Hope it helps!

thanks!

Any estimation for a new release @philippbosch ?

[manosim]

@philippbosch I could help maintaining the project if you want?
