[Bug 1517732] [NEW] Upgrade Elastica to 2.3.1

 

Public bug reported:

Mahara 15.10 is using Elastica 2.0, which is only compatible with
Elasticsearch versions up to 1.5.2.

Elasticsearch is now up to version 2.3, which supports up to
Elasticsearch 1.73: http://elastica.io/2015/10/18/release-2-dot-3-1/

We should upgrade.

It is worth noting, however, that Elasticsearch's latest version is
2.0.0, and the current version of Elastica does not support that yet.
Apparently ES 2.0.0 breaks a lot of backwards compatibility. An upgrade
to support ES 2.0.0 is in progress, however:
