// README
// Magnet Catcher works on any site. There are included the most popular ones
// but don't worry about adding your own or even include * (all sites).
// jQuery is used to do the hard work. Script is safe and stable.
// CHANGELOG:
// 0.42
// + three new trackers added (openbittorrent.com, publicbt.com, istole.it, ccc.de)
// 0.41
// + minor improvement of the hash regular expression
// + new torrent sites included
// + @grant metadata added
// 0.4
// + magnet downloads are now named after the source webpage's title, which is somewhat more informative than bt info hash.
// + magnet uri now contains default tracker address of openbittorrent, which improves startup time and average speed.
// 0.31
// + bug causing crashes in Firefox 5 fixed. Culprit: re() function call rewritten to re.exec() on lines 103, 113.
// 0.3
// + support for Opera and Google Chrome
// + changed jquery source to minified version
// + support for base32 hashes
// + added best torrent sites into included sites
// + magnet links are now appended to site links (were put after)
// 0.2
// + removed bug in regexp - does not match hashes longer than 40 letters anymore
// + better handling of textual end leaf (non-anchor nodes)
// + default set of servers has been inspected
// + other minor improvements
// 0.1
// + initial version
// a function that loads jQuery and calls a callback function when jQuery has finished loading
