Adds search on other sites for google, bing, and yahoo
Let's you run a search on another search engine with just a click. Adds "Try this search on" below search results for Google, Bing, Yahoo, Swagbucks. DuckDuckGo, WolframAlpha, Twitter, Google Scholar, MS Academic
Based on a Russian script http://userscripts-mirror.org/scripts/show/88083
I'm no javascript expert so there are some bugs (if you search for something on google then change the search terms, the script won't pick up on the new search term and it disappears when you click search options on google.) but I don't know enough to fix it.
