XenForo Auto Lock Threads v2.2

Let's your threads being auto locked after a limited number of posts, or after a Date/Time, or even after some Interval.
Good for games threads, spam threads and event threads.

Installation
Upload the DS folder to your XenForo's /library folder (ex: /www/html/forum/library).
Go to ACP -> Add-ons -> Install Add-on -> Install from Uploaded File
Select the addon-DSAutoLockThreads-x-x.xml file
Click Install add-on
Wait for the system to finish installing it
Upgrading
Upload the folder as explained on item 1 of Install procedure, overwritting the files
Go to ACP -> Add-ons -> Auto Lock Threads -> Upgrade -> Upgrade from Uploaded File
Select the addon-DSAutoLockThreads-x-x.xml file
Click Upgrade add-on
Wait for the system to finish upgrading it
Observation:

PHP 5 >= 5.3 version required for it to work.
Developed using XenForo 1.0.4. Prior versions were NOT tested by me. It may or may not work on them.

On the file name, x-x corresponds to the released version (1.0, 2.0, etc)

Usage
Every thread now will show a new link, Auto Lock Options
By clicking on this link, it will open a form overlay, where you can set the limit for the thread.
Input the maximum number of posts allowed, or fill the date/time accordingly, or fill the interval
From ACP -> Applications -> Node Tree -> List Limited Threads, you can check which threads have the auto lock feature, and you can clean the limit any time, clicking on the red X button
That ACP section now have the View thread link, that will open the referred thread in another tab/window, and that is now better organized, filtering threads limited by posts or by date/time
Threads with an Interval will be showed as limited by date/time as well

It's my first add-on. It's here so you can test it, so it may not work so well on your forum as it worked on mine. I know it's not perfect, but got easy on me. If that interests you, then test it and post some feedback. Suggestions and critics are all welcomed. I hope to do more works in the future.
Also, thank you all the development community here, for sharing all your experiences and tips on developing for XenForo. That helps a lot. And a special thanks for Syndol, the one who always listens to my newbies questions.
