Add select all elements toggle

[capJavert]

UI should expose the feature where Jawa can automatically remove :nth-child and similar grouping parts of the selectors to automatically widen out the elements that are scraped.

Example:
User is scraping a homepage of the blog or aggregation websites. There are multiple article/post items. User want's to scape all the titles on the page. If he selects the title in Jawa currently it will scrape only that one title. With this new feature he would be able to check "apply all" or similar UI element which would make the best guess to widen the selector to scrape all titles.

Caveat is that this can be pretty specific to some pages so it will not be the magic bullet but should enable less technical users to scrape content faster.
