* Fix demo-session glob (missing "*" + session_archive_suffix)
* Copy demo-session also when copying settings from older version
* Also add demo-session to recent-list if it was previously unpacked
for new major versions.
* Remove Monitor Model Option
* Remove Monitor Section Option

and (b) sometimes fails or crashes weirdly,
or (c) a plugin dialog gets hidden behind the main window, or ...
Overall the first impression of the program may be horrible when
the first step includes discovering VST plugins.
