[luci] luci Lua modules

Yeah, it was part of a discontinued server project which didn't receive
any updates in years - at some point I decided to throw everything away
which is not in use by core LuCI anymore. However, you can find the old
daemonize() function at [1] - its pure Lua code built on top of nixio so
you can easily port it into your project.

It will probably stay around but not sure if someone will invest work in
porting it beyond version 5.1x - it is unfortunately that the Lua
authors broke compatibility with later releases.

I'm not sure if it will get faded out, the Lua bindings are quite mature
nowadays and common alternatives like Python, Perl or newfangled Node.js
stuff are waay too big for a huge chunk of the hardware base.

I suppose that Lua will be around for quite a while on OpenWrt, it will
just not be part of the default release.
