Use CodeClimate

[baudren]

We could start using Code Climate to have some static code analysis. It seems more efficient than Landscape, as far as I can see - it identifies hotspots, identical code, complexity, etc...

I opened an account for NoteOrganiser, I don't know if it is publicly visible yet. Could you confirm, @egolus?

The page works for me so it looks like it's public. Does it comment with updates in a PR as Landscape does?
