Regression: Draw areas first, then other ways

[stoecker]

1. In the past I implemented functionality, that areas (and parts of multipolygons which have either empty style or area style) are drawn first and later everything else. This does no longer work. They are again drawn over the streets and other ways.

2. Also if I remember correctly the line style of unstyled multipolygon ways (means untagged usually) was set to the line style of the polygon (i.e. style of relation or outer way). Now they are drawn as unstyled again.

Both of these features had been added to improve visibility of more important elements. The alreadyDrawn functionality has been removed especially by Gubaer (also Jiri I think), but it seems instead of improving it, it has only been killed.

Another issue see above bug: members of selected relations aren't drawn on top.

Addition: Disabled objects should be drawn below unfiltered ones.

(In [3307]) see #5078 - untagged ways are drawn with multipolygon style again, removed broken option to skip style cache

(In [3322]) fix #5078 - regressions in drawing code - please test if everything works as expected
