Add Collection.from_items

[jsignell]

Related Issue(s):

• Closes Add ItemCollection.to_collection #1254

Description:

I ended up implementing this the opposite direction from the original proposal as mentioned in the ticket. There are probably more attributes that we can scrape off the items especially once #1521 shakes out.
