Description:
LuaSQLite3 is a thin wrapper around the public domain SQLite3 database
engine.

This commit adds another sqlite3 module for Lua. This is very popular
and in my opinion, suites even better for some projects requiring
sqlite3 in Lua than already luasql, even though luasql is more
versatile since it supports other databases as well. It wouldn't hurt
to include this in the repository. This can also be installed with
luarocks, but I prefer a openwrt package.
