[uMap] 1.0.0-rc.1

[Yohan Boniface]

Hi amigos,

A quick email to let you know I've (finally!) packaged a release
candidate for the 1.0.0 version of uMap.

Please do not update yet your installation, but you can test it on the
usual demo server:

http://umap.fluv.io/

This release is mainly about code organisation and bug fixes, but there
are also a few small enhancements.

Full changelog is available here:

https://umap-project.readthedocs.io/en/latest/changelog/#100rc-1

Highlights:

- Leaflet.Storage and django-leaflet-storage are now merged into uMap:
this should make the maintainer and contributors lifes simpler in the
future

- this version moves to Django 2.x, which drops the support for python
2.x, so python >= 3 is now required

- the permissions panel has been moved from HTML templates to JS as the
others, and this should fix its slowness; please test this with care
and report any issue :)

- added UMAP_CUSTOM_TEMPLATES and UMAP_CUSTOM_STATICS settings, and
umap/theme.css to make customization easier

- filtering in data browser now is also reflected in the displayed
features

- allow to use an unicode character as Marker symbol (in addition to an
URL): this allows to use ✀ or ❶ or even a single letter or number; it's
also possible to use a dynamic property, like {char} that would be
loaded from the feature (and special one {rank} will display the rank
of the feature in the layer)

- added a TablePanel popup template


Thanks for testing and giving feedback! :)
