[Systems] wiki.sugarlabs.org relocation and upgrade

[Bernie Innocenti]

Next Tuesday we'll be moving the wiki from Solarsail to Sunjammer to fix
some long-standing stability issues and also speedup page generation.

The consequent outage provides a perfect opportunity to also upgrade to
the soon-to-be-released version 1.16 of Mediawiki which we've been
running for a while in our development sandbox to test Josh's new theme:

MediaWiki is a very well maintained webapp, there shouldn't be any major
issues for us in their beta2 release:
