MediaWiki recent changes namespace toggler version 0.5 by Greenpickle.

Put the code on any script page you want, such as User:Name/monobook.js,
Mediawiki:Common.js, etc..  There are a few options detailed a bit lower down.
You'll also need the following CSS on a style page of your choice (*.css):

.rcnsthidden {display: none;}

With a little knowledge, this can be modified to, for example, show all ignored
edits in a different colour, or align them to the right, rather than hide them.
Examples:

    Greyed out:
.rcnsthidden {color: #aaa;}
.rcnsthidden a {color: #777 !important;}

    Smaller font:
.rcnsthidden {font-size: 0.8em;}

    Right-aligned:
.rcnsthidden {text-align: right;}

    All three of the above:
.rcnsthidden {text-align: right; font-size: 0.8em; color: #aaa;}
.rcnsthidden a {color: #777 !important;}

To-do:
 - incorporate logs stuff: deletions, uploads, bans, etc. (separate checkbox
   list; created based on what's found in the currently shown RC)
 - make possible with enchanced (grouped) RC
 - hide h4s that have no visible contents
 - extra buttons to toggle all/invert toggle
 - check for existence of indexOf, etc. before doing anything
 - specific page include/exclude lists (requires ns prefix; remember _s)

// Change this to true to make the list below an include list rather than an
// exclude list:

include = false;

// Here, default namespaces can be set; put them in '' or "" separated by
// commas, inside the [].  By default, this is the excluded list:

RCNSTList = [];

// Change these if it'll make styling easier - e.g., use ul/li and create a
// hover menu:

RCNSTbeforecheckboxes = '<span id="rcnst"><hr />\n';
RCNSTaftercheckboxes = '</span>';
RCNSTbeforecheckbox = '';
RCNSTaftercheckbox = '\n';
