tdbm and libcurl bindings for lua 4.0

[Steve Dekorte <steve@...>]

Just put together some bindings for tdbm and libcurl:

- tdbm is a transactional version of dbm (a non-relational key/value 
database).
- libcurl an http, ftp, gopher, etc lib that supports ssl

They're available at:

I've also updated luapickle - a lua table serialization library(this 
version is smaller, simpler and faster):
