[Metalab] searx: leiwande meta web search engine

- Searx may not offer you as personalised results as Google, but it doesn't generate a profile about you - Searx doesn't care about what you search for, never shares anything with a third party, and it can't be used to compromise you - Searx is free software, the code is 100% open and you can help to make it better. See more on github i'm using it now as my default search engine. http://searx.me greets, amir
