Unix man pages updated for Lua 5.2

[Ico <lua@...>]

I have updated the (unofficial) Lua API man pages to Lua version 5.2.

These are groff files which are generated from the Lua reference manual,
I did my best to create acceptable formatting but there might still be
some flaws.

The .tgz archive can be found at http://zevv.nl/play/code/luaman/
