The data table is used to map objects (clients/tags) to the buttons associated
with them. This is done so that we don't have to re-create the button objects
each time this lists are updated.
The problem was that this weak-keyed table was never cleared, because the value
had a strong reference to the key (via the button's signal):
btn:connect_signal("press", function () b:emit_signal("press", o) end)
"o" is the key in the table and btn is reachable from the value. This prevented
the garbage collection of the key. Using a weak-keyed and weak-valued table
fixes this.

Since 3fbb5f1535 "luaobject: emit signals on class too" when a signal
is emitted on some object, it will also be emitted on the class. This means that
we don't have to connect our signals via the "new" signal anymore, but can
instead connect to the signal on the class.
(Of course, the signal on the class gets as first argument the object on which
the signal was emitted)

The tasklist shouldn't care about the tag history or new tags showing up and it
also shouldn't care about tags disappearing on other screens (on the current
screen the tasklist needs to update because the tag might have been selected).
On the other hand, the tasklist really should care about tags being selected and
unselected. This worked before because this causes changes to the focus history.

"a .. b or c" is equivalent to "(a .. b) or c", but we want "a .. (b or c)".
This bug caused an "attempted to concatenate a nil value" error message.
