Toolbaroptions should be better declared

[Waxolunist]

The toolbaroptions are currently read in the root of the options. The disadvantage of this approach is, that it is not possible to declare more granular options. Besides it is bad, because it does not allow to declare other options of type boolean and value true.

Goal is that toolbaroptions are an object of its own. Every non falsy value should initiate the corresponding menu.

This change will break current approach, therefore it is in version 0.3.x.
