Fix buttonbar handling/theme changed handling in lists.

The lists need to copy to a local parent if a list passes NULL as parent in the init. This was before the commit of custom ui vp, but I removed it since I (wrongly) thought using the ui vp as parent would be fine. Let the viewportmanager fire a event in case when a theme-related setting changed and simply the handling in the lists code.
However the buttonbar handling didn't work before anyway, since list code didn't know if the buttonbar was active (it asked a variable which was always false....).
