The Debian AppStream generator flagged both webhttrack desktop entries as
no-metainfo: with no MetaInfo file, the catalog entry is synthesized from
the .desktop file and the package description, which is deprecated and risks
the app being dropped from the metadata catalog.
Add com.httrack.WebHTTrack.metainfo.xml (installed to share/metainfo) for the
main app, launching WebHTTrack.desktop. Mark the secondary "Browse Mirrored
Websites" launcher with X-AppStream-Ignore=true so it doesn't produce a
duplicate, metadata-less catalog entry.
Validated with appstreamcli validate and desktop-file-validate.

Also fixed HTML-escaping issues inside webhttrack
Rationale: The webhttrack script made the wrong assumption that once the "browse" command returned, it meant the user killed the navigation window, and it had to kill the server itself. However, modern browsers tend to "attach" to an existing session (creating a new tab, for example, within an existing window), causing the browsing command to return immediately, thus causing the server to be killed immediately by the webhttrack script. I have rewritten the logic behind, and now the server is able to kill himself if the parent script dies, AND if the browsing client did not make any activity for two minutes. The "activity" can be any browser/refreshed page, or the internal "ping" iframe (which pings the server every 30 seconds). With this model, we *should* be compatible with old browsers, and modern ones.
