/*  id is what we internally use to identify the language.
        *MUST BE* Same as the key so we can always query for it, everywhere.
            Used in: properties, url redirect, lang dropdown
    name is what we display to the user
            Used in: UI
    monaco is how we tell the monaco editor which language is this
            Used in: Monaco.editor.language
    extension is an array for the usual extensions of the language.
        The first one declared will be used as the default, else txt
        Leading point is needed
            Used in: Save to file extension
    alias is an array to be used when looking for the hostname corresponding
        language
