//
// History:
// --------
// 2018.07.10  [1.45] Better error messages & progress bar handling during errors, specially for those who never used check-ins.
// 2018.07.05  [1.44] 10 year anniversary edition! :D
//                    Fixed bug from v. 1.43 where movie titles and people names were getting mixed.
//                    New default highlight color for lists of people.
//                    New & improved way to set color priority (search for listOrder).
//                    Now supporting check-ins list.
// 2018.07.03  [1.43] Added support for lists of people - but since I don't use this feature, I'll only see problems via bug reports.
// 2018.02.16  [1.42] Included support for "https" protocol. There is one local storage for each scheme,
//                    so stick to either http or https browsing to avoid having to download your data twice.
// 2018.01.19  [1.41] New IMDb layout "removed" script buttons, this update fixes it.
// 2017.12.19  [1.40] IMDb FINALLY produces correct CSV files (it took them only a few years to fix this)!
//                    There's also a new "Your Lists" page layout, so a new version of the script is required.
//                    Now two steps are required to fetch the watchlist.
// 2017.03.16  [1.39] New IMDb layout, new highlightTitle()
// 2016.01.27  [1.38] New IMDb layout, new highlightTitle()
// 2014.12.19  [1.37] Work around IMDb CSV bug: https://openuserjs.org/scripts/Ricardo/IMDb_My_Movies_enhancer/issues/Script_doesnt_parse_movies_with_character_in_the_title

// 2013.10.05  [1.35] Fixed bug where script buttons might not show up sometimes
// 2013.09.21  [1.33] Experimental: downloading all lists at once! (http://userscripts.org/topics/131873)
// 2013.09.20  [1.32] Fixed another change in the IMDb site (http://userscripts.org/topics/126010?page=2)

// 2013.05.29  [1.30] Fixed bug in the "tabs" sections (trivia, connections, etc.)
// 2013.05.27  [1.29] Working again after changes on IMDb site; fixed tooltip bug
//                    that could affect navigation (thanks, somini!); fixed tooltip bug where
//                    the tooltip would appear behind another element; highlighting works
//                    on the main page of a title
// 2012.12.06  [1.28] Sorry... fixed a bug introduced in the previous bugfix. :P
// 2012.12.06  [1.27] Changed versioning model (since it wasn't working correctly on Chrome),
//                    fixed small bug where search results were not being highlighted.
// 2012.12.06  [1.26] Fix for IMDb site change, correctly shows how many lists it will load,
//                    should also work with dynamic loaded links and images
// 2011.10.06  [1.25] Workaround fixed Opera regex memory leak; Added code to give
//                    "color priority" for a specific list (see movieColor function)
// 2011.10.05  [1.24] Fixed bug where movie data was not captured if there were no votes for it;
//                    Small changes to try to fix possible memory leaks on Opera
// 2011.09.19  [1.23] Fixed & improved code to handle ratings, now should always show the

// 2011.09.17  [1.22] Small bugfixes; made it work again on Google Chrome
// 2011.09.14  [1.21] Works on xx.imdb.com; made it easier to support movies lists in
//                    languages other than English (if/when they are available)
// 2011.09.09  [1.20] To disable color highlighting for a list just remove its customColors
//                    entry, or make the color = ""; Now compatible with N900 again; Shows
//                    both your rating & IMDb rating in the tooltip

//                    Enable custom lists colors by changing the script code (look for customColors)
// 2011.08.27c [1.15] Automatically reload page when changed sort/view
// 2011.08.27b [1.14] Don't stop downloads if can't find movies in a list; ignore lists not about titles
// 2011.08.27  [1.13] Slightly better handling of download errors
// 2011.08.26d [1.12] Fourth updade in a day! Now sorting option is user selectable
// 2011.08.26c [1.11] Guess what? Now IMDb enabled list configuration... it's not working on all lists, though... XP
// 2011.08.26b [1.10] Less than one hour after uploading this script IMDB changed a few features again! :P
// 2011.08.26  [1.9] Changed how lists are displayed by default; allows manual update of information
