[ANN] Lua FAQ updated

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

Hi all,

http://batbytes.com/luafaq

Thanks particularly this time to Jacob Jay for contributing and Jeff
Pohlmeyer for proofreading, and of course to Patrick Donnelly for
hosting this document.

A change in the layout is now that you may directly refer to the
sections, so that http://batbytes.com/luafaq/#T1.18 will take you to
the section on variable scoping (where I now mention the 'local by
default' question.) The item numbering is now expected to remain
stable.

The C API section could do with more entries, since it appears that
most of the questions here on the list are about it.  E.g. the
question 'What is Userdata?' could do with a good answer.
