Bump version to 2.31.4

The current effect API passes an unnecessary list of windows to
switch_workspace() and forces a window to be passed in when killing
the switch_workspace() effect.

We can simplify the interface to correspond more closely to how
it is actually used and fix these problems:

Remove the actors parameter to plugin->switch_workspace
Remove the events parameter to plugin->kill_effect and rename it to kill_window_effects
Add plugin->kill_switch_workspace

Remove mutter_plugin_manager_kill_effect
Add mutter_plugin_manager_kill_window_effects
Add mutter_plugin_manager_kill_switch_workspace

Remove mutter_plugin_effect_completed
Add mutter_plugin_[minimize/map/destroy/maximize/unmaximize]_completed
