This commit allow user defined delegates to be used as list elements.
This put an end to the endless attempt to cram more features into this
code.
A widget template (non-instantiated) is passed to the arguments and
is created by the common code. It also supports "roles" where some
user defined widgets can replace the old textbox or imagebox.
It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.

No idea what the correct value for this argument is supposed to be, but since
there is no variable "m" in scope, this always uses nil as the value.

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`.
Closes https://github.com/awesomeWM/awesome/pull/313.
Use `beautiful.xresources.apply_dpi` for `common.list_update`'s textbox
margins, and add a left margin for the imagebox, too.
The latter is useful/nicer with the default behavior of an inverted
style for the focused tasklist entry.
