* 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
These days those can be toggled after setup, even while the
session is loaded and engine is running. There is no need to bother
a user very early on with this question about Monitoring.
Because (a) it makes the startup seem "very long and complicated",
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.
