Until now, the logos would display too small on a smartphone.

With this commit, they have been slightly increased in width to make
them a little more visible there.

Until now, only the current grants were written. But that was not
fair.

With this commit, a short history of the project has been added,
mentioning all the relevant institues and grants.

Until now, the supporting organizations section of the Maneage webpage
didn't contain the AEI logo for the two grants that we have been using
to develop Maneage.

With this commit it has been added, along with a short description for
the current grant. Previous grants will also be mentioned soon.

Until now, the copyright years were 2024, but it is 13 days that we
have entered 2025! So it has come time to update them.

With this commit, all the ending copyright years have been changed to
2025.

Until now, the copyright years were 2023, but we have entered 2024 and
it was necessary to update them.

With this commit, the second components of the dates have been updated
to 2024.

Until now, the old pixelated PNG format of CEFCA's logo was being
used. However, recently Marjan Akbari made an SVG replica of the
format and published it on Wikipedia:
https://commons.wikimedia.org/wiki/File:CEFCA-logo.svg

With this commit, this vector graphics logo is being used instead.

Until now, we didn't have a clear link to guide new visitors on how to
start using Maneage! The link to the customization checklist was
deeply burried within the text of the top page and was hard to find
for someone who wants to just get started fast.

With this commit, a "Quick start" link has been added to the top menu
of the Maneage webpage. It will directly go to the customization
checklist within 'README-hacking.md' on Gitlab (which will be up to
date; as we don't yet have a complete and independent documentation,
this is the best current reference). Later, when the documentation is
complete, this link will be changed.

This was suggested by Sepideh Eskandarlou.

Until now the internal and visible copyright years were 2022, but we
have moved into 2023.

With this commit, the copyright years have been updated.

Until now, we hadn't clearly defined what we mean by Maneage being a
program. So viewers of the page could get confused.

With this commit, that old sentence was replaced by a new one written
by Richard Stallman in a private email (hence why he is the commit
author and Mohammad, who pasted it inside of 'index.html', is the
committer).
