A new backend using scripting language mruby

Hi,

I have a new backend for PowerDNS "mrubybackend".
It is using Scripting Language mruby.

You can check it out at:
https://github.com/rhykw/pdns-mrubybackend

It's still a proof of concept and doesn't implement
the complete API.

Any feedback is welcome!!

Have a great new year!

Regards,
 rhykw
