Unmaintained Post Count Rebuild 1.1.1

Ensure posts in deleted threads aren't included in posts counts.

The add-on ID has changed. This version will install as a new add-on. Please uninstall the old version.

I'm not sure if I've fixed or changed anything, but this is a very quick complete rewrite I just did on a 1.4.6 install.

Fixed issue in framework, preventing install.
