          thanks to Fabian Bastin
          (http://www.phorum.org/phorum5/profile.php?61,3024).
v5.2.1.04
        - Enhancement: Added support for the Admin Token required by Phorum
          5.2.11 and beyond.
v5.2.1.03
	- Bugfix: The admin_pre function was set to run a security check even
	  while installing or upgrading Phorum.  Phorum user Marian reported
	  that this derailed an upgrade from Phorum 5.2.7 to 5.2.9a.  Thanks
	  goes to Marian for helping find and fix this bug.
v5.2.1.02
	- Added a number of event flags to be logged in the Event Logging
	  module.  All are logged under the category "Security" and actual
	  failed attempts at login, captcha, override codes, etc will show as
	  alerts while other lower risk events will show as warnings.
	- Check config.php file permissions to ensure that only the owner can
	  read it.  Check for the config.php.sample file as this may also
	  contain database password info if not deleted during the installation.
	  This can help avoid database intrusion on a shared host but this check
	  can be disabled if this is not a concern.
	- Fixed numerous PHP errors.
v5.2.1.01
	- Added the ability to choose whether to ignore the captcha on the first
	  login attempt.  Basically, this assumes that a bot isn't going to guess
	  your admin password on the first attempt, so why use a captcha the first
	  try.  With this setting enabled, the captcha is displayed, but you do not
	  need to enter it on the first attempt.  If the incorrect password is
	  entered, each subsequent attempt will require the captcha.
	- Fixed numerous PHP errors.
v2.00
	- Updated for Phorum 5.2 compatibility
	- Removed the ability to centrally manage users with admin access as this
	  can be done from "Edit Users" in Phorum 5.2.
	- Removed the ability to log admin logins as this can be done from the
	  "Event Logging" module in Phorum 5.2.
v1.07
	- Added the ability to monitor admin IP usage and block hackers from using
	  a valid cookie to access the admin area without logging in.
	- Added the ability to restrict admin logins to a scheduled time block such
	  as 9 AM to 5 PM, as determined by your server's time offest by your time
	  zone selection in the "General Settings" section.  A warning will be
	  displayed at the top of the Admin section when you have less than 15
	  minutes before the scheduled time is up.  After that, you have the option
	  of allowing an override code to be sent which would allow for an hour of
	  access.
	- Updated the IP restriction function to allow the sending of an override
	  code to users with admin access.
	- Updated the code to be compatible with the coming "admin_pre" hook in
	  future Phorum releases.
v1.06
	- Added the ability to send the lockout override code to the email address
	  of the user who failed to login, but only if that user has admin access.
	- Added the ability to centrally manage all users who have been granted
	  Admin access.
	- Added the ability to add a captcha to the admin login.
	- More changes to the module's settings interface to add features and help.
v1.05
	- Fixed a bug in the title monitoring code which would not replace a
	  hacker's code with the proper title.
	- Added the ability to search through the settings saved from the admin
	  area.  This is useful if you are looking for all instances of a
	  hacker adding an iframe or the hacker's name to your site from the admin
	  area. The results require some knowledge of the Phorum framework.
	- Changed the module's settings interface to incorporate the new features.
v1.04
	- Added the ability to restrict admin login to set IP addresses.  If this
	  is enabled there is also an option to allow the sending of an override
	  code to the system email address.  This allows the system admin to access
	  the admin section even from a restricted IP address after receiving the
	  override code via mail.
v1.03
	- Tweaked the admin lockout feature to display properly.
	- Added the ability to allow a lockout override code to be sent to the
	  system email address.  This should allow the system admin to login if
	  a password is mistyped on accident but should still styme hackers and
	  bots.
v1.02
	- Recoded the logging of admin logins.  Should work better now.
	- Added the ability to lockout an IP address if too many failed
	  admin login attempts are made. Requires added "admin_pre" hook.
	- Added the ability to clear out the log of admin logins.
v1.01
	- Added the ability to log admin logins.  Requires added "admin_pre"
	  hook as described under installation above.
v1.00
	- Started
