[ANN] Updated uFAQ (Unofficial Lua FAQ)

[steve donovan <steve.j.donovan@...>]

Hi all,

http://luafaq.org/

has been updated. I've tried to cut back on the opinions, and refer
more closely to 5.1/5.2 differences in the text.

Luiz suggested the new name uFAQ, which is how it is now referred to
from the official FAQ.  He gave some good CSS tips, and I'm now
semi-consciously styling it like that document.

It's feeling a little long, and is probably uneven in coverage.  So
any suggestions for refactoring would be welcome. In particular the
sections on web programming and C/C++ bindings could do with some
love.
