[calligra] krita: save mirror, erase, composite op and mirror settings to presets

[Cyrille Berger Skott]

I do agree with Silvio that is confusing for users. However, lets work on 
suggestion for improvement :)

What I am thinking is that the opacity and composite ops mode should be also 
visible in the editor. And then the toolbar should be perceived for users as 
shortcut to access the most common brush options (ie scale, opacity, composite 
op).

And I do think that if we do like this it should work nicely for users.

As for the broken presets, I suggest opening a bug report with an attached 
presets.
