Fixes #9444

Fixes #9458

This is a regression from e3050697

The default GTK link handler does not work on Windows and Mac

Fixes #9453

The package has been fixed in the mingw repos

- Preferences: Add options for display in banner, tab, roster
- This makes the chatstate Plugin obsolete

This is needed so we can query the current chatstate colors in cellrenderers

- Only show one notification at a time
- Fix pylint errors

- Rename notify to notification
- Move get_show_in_roster() to gtk.util
- Move get_show_in_systray() to gtk.util

With this Gajim loses the ability to draw animated GIFs in the Roster

GIFs have numerous drawbacks:

- We cant add them to the IconTheme, which means we need a different interface to load them
- The IconTheme scales all icons we load for the current scale (HiDPI)
- The animation causes many updates to the Roster, and causes high cpu usage

Fixes #8814, #8655

This is needed for tests to work

- Use parse_datetime()
- Improve tzo node validation
