I love this plugin, can we get support for duckduckgo

I am using this plugin from last few days and it's working as expected, I have no complaint about it, It's work properly.

I am using duckduckgo for doing programming related research, can we get support for duckduckgo. I can contribute on the programming part.

let me know, if anyone interested, this plugin can be extended to support more Search engine and it would be helpful for everyone who use other search engine than google.

I think support other SE, create new branch and replace the searching domain and update match rules.
keep the master simple and stable.
