restructuring suggestions

[Necktschnagge]

I changed some things, made some experiments.
Let's discuss this and apply some further enhancements before merging into your branch.

on/ off switch for solver @Necktschnagge
https://stackoverflow.com/questions/14780517/toggle-switch-in-qt
no need to place solver in status bar

-> #100

[r0ost3r]

may be we should use QStatusBar::insertWidget or QStatusBar::addWidget for Color instead of PermanentWidget @Necktschnagge

[Necktschnagge]

Color ball looks nice in code @r0ost3r.
Can you add it to the status bar?

[Necktschnagge]

Things you can implement @r0ost3r

[Necktschnagge]

Can you add the requested additional QLabels here,
you may also add your color ball here.
I'd also be fine with just a Label with empty space and the correct color.
Feel free to find your favourite solution.

[Necktschnagge]

@r0ost3r Can you add the labels as requested in these comments?

[Necktschnagge]

Here you'd have to add the initialisation code for additional labels or other widgets inside status bar.

I don't want a toggle switch. Furthermore, solver will have more modes than just ON and OFF.

No, let's stick to addPermanentWidget.
The other methods are intended to add labels that can be obscured by temporary messages.

That's not so nice.
Once we have too many labels we can start thinking about which of them are less important than others.

Let's code the rest together @r0ost3r
