[Systems] Re-enabled account creation on wiki.sugarlabs.org

[Bernie Innocenti]

Hello,

today Sebastian and I re-enabled user creation in the main wiki.

Hopefully ReCaptcha will keep spammers away, but please watch out for
suspicious activity and don't hesitate to disable user creation in case
of another wave of links spam.

By the way: I'll be traveling in Italy from tomorrow until May 14.
Connectivity should be good, but I might be away from all keyboards for
extended periods. Please watch over our machines and don't hesitate to
contact me if needed (my usual phone number should work).
