When the selection that is watched by an active selection watcher
changes, then the signal "selection_changed" is emitted on the watcher.
This signal has one boolean argument that indicates if the selection is
owned. This means that this argument is false when the selection owner
went away and the selection now has no owner at all.

These objects are created via e.g. selection_watcher("CLIPBOARD") to
track the CLIPBOARD selection. They start watching when their .active
property is set to true and stop when this property is unset again.
This commit implements the Lua side of that: A list of active watchers
is kept and updated when needed.
The next commit will add the X11-side of this so that these objects
actually do something.

This commit adds the necessary method calls to setup the class and also
so that xfixes selection notify events can be handled. Currently, these
are empty functions, but later commits will fill them.
