Did a quick editing pass

A couple of comma's that should be there, and chopping a wordy sentence down to an adverb. I promise I'll make some non doc/grammar contributions soon. I've been using Marionette for 2+ years now, and would like give back to the project that's given me so much.

No more return false from onBeforeClose

You can no longer return false from onBeforeClose to prevent a view
from closing. This behavior was inconsistent with the rest of the
library, and would require far too much logic to respect in all cases.
Instead of returning false, you should handle your logic *before*
calling close on the view.
