New possibility to configure ckEditor in config.yml.

The array `wysiwg.ck` holds the config values. `__footer.twig` traverses the values into javascript.

In `bolt.js` we interate through that array and apply `key => value` to ckEditor `config` var.
Commented out additional `wsiwyg.ck` config options
CS fix
Merge pull request #294 from mablae/fix-CkEditorSettings
