Prefer selected text over detecting the article

Articles on franceinfo don't work, so it would be great if one could simply select the text instead of relying on detection.

P.S the included version of readability might be a bit old too. Firefox uses a custom and maintained version. It might be interesting to update the script.

would love this with a context menu, like select the text first, right click, and have a "speed read" option
