This fixes #6558.

LanguageLayer allows specifying language-specific prefs in the following manner:

{
    "spaceUnits": 4,
    "language": {
        "html": {
            "spaceUnits": 2
        }
    }
}

Language layers are added to user and project scopes. Path layer will take precedence over language layer.

LanguageLayers could be used by #7362. Related to PR #6409 (which creates a special event to inform language changes) and should be taken into account by whichever lands last.
