Hides scripts for popular browser games and social networks as well as scripts that use "foreign" characters in descriptions, when browsing or searching scripts.
i.e. it filters any/all of these 4 categories:

• Games: scripts for browser games like Kingdoms of Camelot, Mafia Wars and Ikariam
• Social Networks: scripts for general purpose social networking sites like Facebook, studiVZ and VKontakte
• Non-ASCII: scripts that use non-English characters in description (accents, umlauts, cyrillic letters, ...)
• Clutter: obvious spam, titles like "asdasdasd", description = title, title < 6 characters, "just a test", scripts for themes/dark/night mode (because they are, in effect, userstyles).

The filters list appears just below the "Announcements" table (i.e. on the right).

Note: you may uncomment line 37 (and comment out line 38), in order the filtered scripts to be highlighted khaki -instead of hiding them- so that you can check which scripts have been filtered.

This is a modified version of this script: userscripts.org Bullshit Filter (by kuehlschrank).
Thanks a lot to kuehlschrank for making another great script.
Thanks a lot to valacar for the refactoring.
