Require members to be x years old to view certain topics

This is a small mod that lets you require members be a certain age before they're able to view a forum. This simply takes the date of birth in their profile and subtracts it from the current year. I would like to thank ntd1712 for his inspiration to make this mod. Thanks!

Add Below:

'age_required' => 'You are not old enough to view this forum',

Now open up your admin CP -> SQL Management -> SQL Toolbox

Goto where it says "Run Manual Query" and enter:

ALTER TABLE `ibf_forums` ADD `age_required` int(3) unsigned NOT NULL default '0';

Click on run query and it should be good. Note: If you don't use the prefix ibf_ then change it in that query.

That's it! Now you can set the age for each forum in the admin CP. Admins bypass this check.
