Add TEXT_PLAIN as a drag and drop target. And accept TEXT_PLAIN as a target at CompleteDrop(). In the function classify the word and make the URL.(Linux)

If the drop source is not URL, use the source as plain text and pass it to tab_strip_controller and classify it. To pass if the source is URL or plain text, use is_plain_text flag. (Mac) 

patch from takano.naoki@gmail.com

BUG=42797
TEST= 1. Open any site which has text. (news.google.com) 2. Select 2-3 words of text and drag n drop selected text to tabstrip. 3. Chrome opens a new tab with search results (using selected search engine in preferences).
