[OzzModz] Force Ignore 2.0.1

2.0.1

Fix: Properly uninstalls columns added by the addon in the xf_user_ignored table
Change: Now will remove any forced ignores added while running the addon
Added: Option to hide the "Show ignored content" link in threads so users can not click on it to see ignored content.
Added: A cron to turn off the option "Add error logging for debug purposes" in case you forget to turn it off after debugging with Ozzy47. The cron runs every ten minutes.
