This commit changes some tables that are used for per-screen stuff to have weak
keys, so that the screens can be garbage-collected, if needed.

Because all our Lua code can now work with screen objects, most of the uses of
s.index that the previous patches added for reaching this goal can be removed
again.

This is a weak table whose entries might be removed by the garbage collector.
I'm not sure if this will every cause problems, but it's better to be prepared
for tables having "nil holes" (which would mean ipairs ignores some entries).

The code already tried to handle this correctly, but at some point it used the
wrong variable as the screen number...

Again, instead of directly connecting to various signals for updating a
tasklist, this commit changes the code so that there is just a single, global
connections and based on this a weak table with all tasklist instances is used
do the updates.

This allows the "label" callback to adjust the textbox itself.
`tasklist_label` is changed to make use of it and supports new style
arguments: `font_focus`, `font_urgent` and `font_minimized`.

When windows are set as "above", they will basically behave as "ontop"
(under normal circumstances) and therefore an indicator is useful to get
displayed in that case, too.
Closes https://github.com/awesomeWM/awesome/pull/325.
Currently `tasklist_update` gets triggered often, because it listens to
a lot of signals.
This patch makes it only call the last one through `timer.delayed_call`.
