Martin Gräßlin 9f976a4b8d Support multiple event types in X11EventFilter
Summary:
So far the X11EventFilter only supported one event type. But most
usecases for an X11EventFilter require to support multiple event types.
E.g. a filter listens for both key press and key release.

This change extends the internal X11EventFilter to support multiple
types and Workspace::workspaceEvent makes use of that.
