the png files are no longer part of the distribution, and have been
replaced with svg files

to facilitate the migration we'll keep those few png files around for
now, and migrate to the svg equivalents at a later time

the important bits are the css files and the webfonts

translate content files earlier in build, fix #30

Closes #30

See merge request !98

using the hatch buildsystem makes it impossible to install the plugin
via local path reference in requirements.txt like the other plugins

absolute submodule URLs are now supported in CI since gitlab-runner
v15.11.0, see https://gitlab.com/gitlab-org/gitlab-runner/-/blob/main/CHANGELOG.md?ref_type=heads#new-features-18

also drop the note about the need to build lektor twice for lektor-scss,
this is inaccurate when the plugin is properly shipped, either via
packages/ or the virtualenv (but not both)

when upgrading to this version of lego, individual web projects should
remove their own submodule registered at packages/lektor-scss and
update their requirements.txt file to point to lego/packages/scss

this will fix the issue with scss/css not being compiled during the
first lektor build

bring users directly to the new sign-up form hosted on donate-neo

needed for ci to tell whether it should build once or multiple times

this moves the compilation of .po files and translation of contents.lr
files earlier in the build process, in `on_before_build_all` instead of
`on_before_build`, to ensure that the build queue accounts for the
alternative content files (`contents+*.lr`) during the build process,
instead of requiring multiple (expensive) build runs

the caveat is that translated alternative contents files are now only
produced during a full build, which likely breaks "on-the-fly" creation
of those files when authoring using the Lektor web admin interface

While the checkbox persistence mechanism is clever for not requiring
javascript, it only really works for reloads of the *same* page/url. The
checkbox only remembers its state on a given page, not all pages of the
same site. For example, even if the visitor closes the banner on the front
page, it will be shown when navigating to /about, and so forth.

This leverages the browser's sessionStorage to remember when the banner
is closed, and persists for all pages of the same website until the browser
session or tab is closed, which should be much more convenient for casual
visitors.

turns out that _donate.scss is actually processed on all websites, so
this doesn't work, so instead just prevent the template from generating
the button html on donate.tpo
