Entries get updated when field slugs change

[rubenvereecken]

Uses a virtual old.slug to keep track of the old Field slug. If it changes a post save will make sure all related Fields get renamed as well. Should be changed along with the rest of the changes for #168 (assembly).

Hey @rubenvereecken, looks great, could you add a test for it?

[rubenvereecken]

I only ranted 5 times. There's a minor edge case I haven't found after hours of search. It only happens when Mongoose does something quirky so virtuals get lost along the way. We'll have to be careful with updates and such since those circumvent middleware - I've always tried avoiding them.

Anyway, works like a charm for our use cases.

Yeah, that Model.update thing (going without middleware) is kinda lame. I know where mongoose is coming from, passing it through directly to the Mongo client, but still: could be an option or something... Will take a look at this over the weekend, looking forward to it :)
