 // @description Hide answers and comments on Puzzling.SE questions until you want to see them.
 // @grant       none
 // @include     http://puzzling.stackexchange.com/questions/*
 // @version     0.5
 // ==/UserScript==
 
 // Changelog:
 // 0.5.1    By Joe: Directly navigation to a comment or answer now doesn't hide anything, as you've already seen
 //                  the content anyway and hiding it is just annoying.
 // 0.5      By Joe: Added the option to only enable Empuzzler on specific tags, and the option to automatically
 //                  show all spoilers.
 // 0.4.1    By Joe: Don't bother hiding the comments section when there are none, and same for answers.
 // 0.4      By Joe: Less stuff gets hidden (eg. post-answer box), moved hide/show answers beneath #answers-header,
 //                  fixed English grammar on buttons, show number of comments that have been hidden, stopped a button
 //                  showing if there is nothing for it to reveal (no answers means show-answer button never appears)
 // 0.3      Buttons made larger. Added auto-update. Merged clean-up by Joe (Puzzling.SE user 2518).
 // 0.2      Show Everything button added.
 // 0.1      First version, with show comments/answers buttons only.
