use table.unpack on Lua 5.2

[moteus]

I try Orbiter with Lua 5.2 and he works.
Except
lua52: G:\lua\5.2\libs\orbiter\lua\orbiter\init.lua:47: attempt to call global 'unpack' (a nil value)
and use module function in some examples.
if run lua52 -e "unpack=table.unpack"
then all warks. (except trylua)

PS. Do you think about use lhttp-parser?

Thanks, that's easy to fix, as is trylua (while keeping 5.1 compatible)

It was fairly straightforward to use code from LuaSocket for parsing requests. I did not want any other external dependencies.
