[PoC] Visualization: Update to Bootstrap 4.6.1

[EwoutH]

Proof of Concept: Update from Bootstrap v3.3.7 to v4.6.1.

It also updates bootstrap-slider to 11.0.2 and bootstrap-switch its latest commit, Bttstrp/bootstrap-switch@2b316be.

To-do (any help is appreciated!)

• Check the Migrating to v4 guide and implement necessary changes
• Check if all files are necessary.
  • mesa/visualization/templates/fonts can probably be removed since built-in fonts are now used.
  • In mesa/visualization/templates/css/ the bootstrap-them files need to be updated of removed.
• Test as much models as possible.

My working branch is bootstrap-4. Feel free to work from there!

The branch can be installed with pip install git+https://github.com/EwoutH/mesa.git@bootstrap-4 for testing.

@EwoutH #1195 might be relevant to minimize future diffs of this JS/CSS dependencies updates.

[rht]

@EwoutH it should be easier to upgrade Bootstrap now. Also, if you are up for migrating the installation of the other JS dependencies to the method used in #1220.

[rht]

All the JS deps have been removed from the repo. They are now downloaded on-the-fly during setup.py.

[rht]

Superseded by #1282.
