Well, I skipped duplicating all member functions of Format and started with 
the second step:
- breaked the inheritance, instantiate Format
- made this instance available through Format* Cell::format()
- replaced all calls cell->foo() with cell->format()->foo()

I will outline the problem in detail:
- a virtual method Format::formatChanged() exists, which does nothing and is 
called in every Format::setFoo() method
- Cell reimplements Cell::formatChanged(), which sets the two CellFlags
-> each call of Cell:setFoo() will set the flags

So, I have to reimplement each Cell::setFoo() method and set the flags in each 
of them, if there's nobody with another solution.

Bye,
Stefan
