/*
*  Things to note: 
*       - The users listed in the twinkleblacklist array will *not* be able to use Twinkle, even if they have it enabled as a 
*         gadget.
*       - The search method used the detect the usernames in this array is case-sensitive, so make sure that you get the
*         capitalization right!  Always capitalize the first letter of a username; this is how the software formats usernames.
*       - The users on this blacklist will remain so until they are removed.  The only way to restore one of these users' access to
*         Twinkle is to remove his/her name from the list.
*       - Make sure that every username is wrapped in straight quotation marks ("" or ''), that quotation marks or apostrophes 
*         within the usernames are preceded by a backward-slash (\), and that every name EXCEPT THE LAST ONE is followed by a 
*         comma.  Not following these directions can cause the script to fail.
