Runtime: work around 1s delay added when using twisted reactor's callLater.
Since wxPython4, using wxReactor from non-main thread was producing
exceptions in wxWidget's C++ code. Then reactor.run() was called from
main thread, and runtime's worker was delegating calls to reactor
with callLater(0, callable).
While this worked perfectly with wxReactor, it did introduce an unexplained
1 second delay to each worker call when using nomal linux reactors
(i.e. without wxPython). As a workaround reactor runs in a thread when using
twisted without wxPython

List widget is a svg:group, list items are labeled elements
in that group.
To use a List, clone (svg:use) one of the items inside the widget that
expects a List.
Positions of items are relative to each other, and they must all be in the
same place. In order to make editing easier it is therefore recommanded to
make stacked clones of svg elements spread nearby the list.
