Get the item's attributes corresponding to a memo

Related to : #84

We need to see the item's attributes in the Hypertopic Item for our function : Hypertopic/Porphyry#191

For now you can access to:

GET http://cassandre.hypertopic.org/item/enseignants-decrocheurs/deb51701fe5e555acf3a765a30115e04

{"rows":[
{"key":["http://cassandre.hypertopic.org/text/enseignants-decrocheurs/deb51701fe5e555acf3a765a30115e04"], "value":{"item":{"corpus":"enseignants-decrocheurs", "id":"deb51701fe5e555acf3a765a30115e04"}}}
]}

And we need to access other attributes like :

• Interviewe (the person being interviewed)
• Author (the person who interview)
• Date of the interview

The fix is available on UTT's Cassandre server:

I did it both for item (as asked) but also for corpus (which is the efficient way to go through this:

• http://cassandre.hypertopic.org/item/enseignants-decrocheurs/deb51701fe5e555acf3a765a30115e04
• http://cassandre.hypertopic.org/corpus/enseignants-decrocheurs

As you can see, all attributes (e.g. enquêteur and date) are now got. Be careful, the values are either a string or an array of strings.

@christophe-lejeune I pushed the fix on v2.
Commit 8aad2e6 could probably be cherry-picked (and amended) for v3.
