11532	Create editor#addContentsCss() method	Marek Lewandowski	Marek Lewandowski	"We should create more convenient way to add custom css files. Now we accept as `editor.config.contentsCss` string or array of strings which is ok, but if we want to attach to it extra css styles in plugins, we have to do some extra checking. Such code is redundant.

Method should be editor member, so we will end up with `editor.addContentsCss()`. Method itself should be injected from `wysiwygarea` plugin, since `contentsCss` works only for classic editor.

Method should accept as its parameter a string."	New Feature	closed	Normal	CKEditor 4.4.0	General		fixed
