In the 2.5.5 version of the official IOTA wallet, "Reattach" seems to have been replaced with "Promote". What does Promote do that Reattach didn't, and how does it improve transaction confirmation?

What exactly is being stored in the Tangle if I send a set of data to someone? Is the whole data stored in the Tangle or does the data just pass through the Tangle. Is it just like putting a bag in an empty train and someone at the next station…

Is there a difference between branch and trunk transactions?
I understand that a transaction confirms two other transactions (branch + trunk).
