Crystal-web

This release allows more kinds of advanced sites to be downloaded,
including sites requiring login and sites relying on JSON APIs,
especially those with infinitely scrolling pages.

Projects can now be opened in a [read-only mode] such that
browsing existing downloaded content will never attempt to
dynamically download additional content.

Advanced manipulation of projects can now be done from a
[shell] launched from the command-line interface.

Last but not least, [Substack]-based sites are now recognized specially and can be
downloaded effectively without creating an explosion of URL combinations.

This release primarily features better support for large projects and groups.
Downloads of large groups are dramatically faster and now only require a
constant amount of memory no matter how large the group is. Also a progress bar
is now displayed when opening a large project.

A few more link types in CSS and `<script>` tags are now recognized.

Last but not least, phpBB forums are now recognized specially and can be
downloaded effectively without creating an explosion of URL combinations.
phpBB support is still experimental and likely requires additional tuning.

Several first-time-launch issues were fixed. And domains are now recognized
in a case-insensitive fashion, eliminating duplicate URLs within some sites.

Our first beta release brings support for downloading more complex static sites,
recognizing vastly more link types than ever before. It also supports various
kinds of *dynamic* link-rewriting, beyond the usual static link-rewriting.

Additionally the code has been modernized to work properly on the latest
operating systems and use newer versions of the BeautifulSoup parser and
the wxWidgets UI library. Unfortunately this has meant dropping support for
some older macOS versions and Windows XP.
