[XeTeX] xelatex.org wiki spam -- wiki got (almost) reset

[Mike "Pomax" Kamermans]

  hi all,

even though wiki.xelatex.org hasn't been used a lot, someone decided it 
would be a great idea to "SEO" spam it and drop about 100,000 spam 
articles on it =)

I had to clear it, and restored the base pages that I could see as 
publically linked, but some information may have been lost, and user 
accounts definitely got lost. I'll be setting it up so that it'll be 
harder for bots to register (probably captcha, maybe approval based?) so 
as a heads up: it might be in a state that no longer reflects the latest 
information that was on it =(
