Ignore certain ESReality users without breaking the thread structure. Blocked posts are replaced with a placeholder, which can be clicked to show the contents.

At this time, the list is managed through the "ESR User Ignorer: Manage List" menu command. This might change eventually.

There is also a menu command provided to change the color of the placeholder text.

This script currently only works with Firefox (Scriptish or Greasemonkey), since Chrome doesn't support GM_registerMenuCommand.

Let me know if you find any issues.
