couch.js Database.view() should default to {reduce: false}

[Jason Gerard DeRose]

This is an idea James Raymond suggested quite a while ago.

The CouchDB API assumes ?reduce=true for views that have a reduce function. The problem is that for code that only uses a view non-reduced (regardless whether there is a reduce function), this code breaks if you later add a reduce function.

The CouchDB API would have been better off defaulting to ?reduce=false, and so we're faking this behavior in our view() and view_sync() functions.

In 12.07 we changed this behavior in Microfiber, and it's proven quite useful. So now we're changing this in couch.js also.
