Another Update Time!

Today I included a bunch of fixes for functionalities and a critical bugfix which caused database errors in some cases.

v1.4.5rc3

- Fixed rare error with secondary usergroups being stored in the wrong format causing a Database Error
	(When updating the plugin file, a function repairs all existing database entries once)
- Fixed new user sometimes not being assigned the correct usergroups when registering/linking/unlinking
- Fixed scheduled/maintenance tasks not updating steam user's usergroups correctly
- Fixed stc_cache using object references instead of the actual values
- Fixed the user's display group sometimes not updating correctly
- Fixed scheduled/maintenance tasks clearing the cache, even if memcached system is used
- Fixed scheduled/maintenance tasks sometimes not writing their output into the logfile
- Fixed some typos/errors in the options description text
- Added the option to force an email address in quick register
- Added the option to force the primary steam usergroup as the display group
- Added the option to immediately check if the user is member of the specified steamgroup. This should be disabled if the steam
	group is too huge, (remember that for each page the script needs to query, the registration process is delayed 1 second)
	in which case the correct steamgroup dependant usergroup is assigned the next time the scheduled task runs.

You'll find a small patch process when updating the plugin file. Older versions of the mod just appended additional usergroups to the existing ones, this could lead to invalid strings like ,1 or 5,,6 which would cause database errors if they appeared. The patcher fixes those entries and the updated addon will make sure that this won't happen again.

Next are a few new options, the important ones being that you now can force steam users to enter an email address. At the beginning I thought that new users shouldn't be bothered with having to enter an email address but I respect many forum owners want to be able to send those users emails nontheless, so you're now able to turn on quick registration but have the user to enter an email address. This of course doesn't affect existing users which didn't enter one.

Next is the improved update functionality for handling with additional usergroups when a user registers with steam connect and is in the specified steam group. Last time this didn't work quite well, so now everything revolving about those groups and linking/unlinking forum accounts should work as intended.
Additionally, the scheduled job which keeps those associations updated runs every day at 4:00 am. If you want to increase the interval or change the time, you may do so in the scheduled task section of the admincp.

What you'll notice is a linkback at the footer of your forum to this vb.org mod page and to steam. Reason is, that steam does actually require a linkback to appear on any sites which use their API. This change follows the requirement and appends a linkback to this mod if someone is curious where to find this addon. This doesn't give me any benefits like revenue other than more popularity for the mod which again doesn't generate any money for me directly. You are welcome to donate a small amount if you really want to remove the backlink to this mod page, the steam backlink however must remain because I don't have any power over their rules.

As always, backup your forum before updating, download the newest archive file, upload all contents inside "upload" into your forum overwriting existing ones, then upload the new xml plugin file in your admincp choosing to update existing products.

Let me know if any issues come up.
