// Version 2.2
// - rewrite using DOMNodeInserted and getElements* to support Chromium too
// - enable on encrypted.google.com
// - try to fix new-style classless links in search results (/url?q=...)
//
// Version 2.1
// - enable on plain Google search page, now it works with Instant too
//
// Version 2.0 (Direct Links in Google Search)
// - fork "Less Google", which is not working any more, and rename
// - enable on all Google top-level domains (only .com and .ca in Less Google)
// - enable on new HTTPS search pages (HTTP still supported, just in case)
// - remove deprecated @exclude patterns (search URLs have been changed)
// - don't allow any "onmousedown" link modifications
//
// Version 1.1 (Less Google by @clump)
// - change include to only apply to search results
//   (maps and images are too slow)
//
// Version 1.0 (Less Google by @clump)
