LuaRocks maintainership

[Alexander Nasonov <alnsn%yandex.ru@localhost>]

LuaRock 3.1.0 is out but I don't have any time to update it.
I have a patch for 3.0 version but it's half-baked and it doesn't
work without tweaking a config file. It should be easy to ship
with a good version of the config but I don't have any spare
cycles at the moment.

Feel free to take maintainership. I'll send you what I have and
I can tell what was broken in my update.
