Support for dnsmasq version 2.63

Dear SynoCommunity,

Here a patch that add support for the dnsmasq server version 2.63
Dnsmasq is a dhcp and dns server with a lot of options.

This patch contains :
  - A patch file to add support for autoconf on this versionof dnsmaqs
  - Contains a minimal ui to edit/check the configuration and see some logs files

I created this one since my new nas ( DS413 qoriq ) was not supported by the package intially made by Robert Pollai .

Tested on DS413 ( qoriq )
I would be glad to maintains the package.

Feel free to comments.
