Manuscript default language as a PROJECT preference

While most write only in one language or are monolingual, some of us are multilingual and write in at least two different languages.

Currently Scrivener lets you set the (spelling) language on an APPLICATION basis, the spelling is checked based on that. But on a single day I may work on manuscripts in different languages and am forced to change the application settings every time I switch between projects.

If the MANUSCRIPT language is stored as a project preference, then the user has to set that only once in the lifetime of a manuscript rather than have to deal with that every time the user switches context.

I’d like to add one thing to this (it isn’t really a +1, I promise): working in different languages isn’t just switching between French and English, but also includes needing to switch between US English and UK English.
