Unmaintained Template File Opcache Invalidate 1.0.0

This super simple but really useful add-on is for forums that meet the following requirements:

• Serve templates as files
• Have Zend Opcache enabled
• Have the opcache renew time set to a larger value

When a template is changed, it may not update immediately due to the cached version still being used.

This fixes that. It'll invalidate and recache a template file when it is changed - meaning the changes update immediately, and the files are cached before a visitor accesses the site.

This should make viewing changes easier, as you won't have to reset the cache for changes to immediately take.
