This reverts commit 6ddfd7f7.

This makes no sense in expert mode either but is harder to solve. :)

Also add controls to non-expert mode.

Since there is not dimension-tab is this mode, the controls are placed 
here.

Everybody is considered expert but role 'developer'. The host 
application allows not saving the unit when rights are insufficient, so 
the editor needs not to take care of that. Having full rights allows for 
better inspection of units even if it can't be changed(saved).

So they work within standalone dialogs.

This fixes Tables which houses elements without dimensions.

Now always use grabbing when dragging.

Defaults to 4 when re-activated. This is easier to code.

- Remove fieldsets
- Change structure visuals for combo buttons
