ccsm: Fix TypeError when calling Gtk.Menu.popup() with invalid number of arguments.

It fixes this error:

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/dist-packages/ccm/Settings.py", line 723, in ButtonPressEvent
    self.Popup.popup(None, None, None, event.button, event.time)
TypeError: popup() missing 1 required positional argument: 'activate_time'

Replace the deprecated Gtk.Menu.popup() method with Gtk.Menu.popup_at_pointer().

Check GTK version on startup and exit if it is less than 3.22.

Steps to reproduce:

- Start CCSM.
- Open any plugin settings that have a list, e.g. Animation plugin, or Wizard plugin → Gravity tab.
- Click right mouse button on the list.

A context menu should open. No exception should be printed.
