/**
* Name: Admin Controls
* Author: Shish <webmaster@shishnet.org>
* Link: http://code.shishnet.org/shimmie2/
* License: GPLv2
* Description: Various things to make admins' lives easier
* Documentation:
* <p>Lowercase all tags:
* <br>Set all tags to lowercase for consistency
* <p>Recount tag use:
* <br>If the counts of images per tag get messed up somehow, this will reset them
* <p>Purge unused tags:
* <br>Get rid of all the tags that don't have any images associated with
* them (normally they were created as typos or spam); this is mostly for
* neatness, the performance gain is tiny...
* <p>Convert to InnoDB:
* <br>Convert your database tables to InnoDB, thus allowing shimmie to
* take advantage of useful InnoDB-only features (this should be done
* automatically, this button only exists as a backup). This only applies
* to MySQL -- all other databases come with useful features enabled
* as standard.
* <p>Database dump:
* <br>Download the contents of the database in plain text format, useful
* for backups.
