Overhaul the config system with Lua

[朱江]

Hi all,

I want to overhaul the config system with Lua, and it will be my GSoC 2014
project. Here is the
proposal<https://docs.google.com/document/d/1azZm8WHBiT_oaQ1fEhUWGiYWyn4hvwxEkMXqf1aR00g/edit?usp=sharing>
.

I will create a wiki in my site soon. Please let me know if you have any
good ideas about the new config system. They will not be a part of my GSoC
project, however, I will do this work continuously after GSoC.

One more thing, as I wrote in the proposal, I just want to give something
back to the community, so I will do this work even if I'm not accepted
participating GSoC. Just let me know if you have good ideas, because it is
you who use config everyday. Your advices are very important to me and the
project.

Best regards,
