Auto-prune users once per month

[kh99]

I put together the attached file, you just need to put it in includes/cron and then do "Add New Scheduled Task" in the adminCP, and enter pruneusers.php as the Filename. Also, I used "Deleted {1} inactive users awaiting confirmation." as the log phrase ({1} is the count of users deleted).

I got the code from admincp/user.php so it should do the same thing as pruning users from the adminCP. It probably does more than necessary for "Users Awaiting Email Confirmation" (for instance it assigns any posts or threads to "guest"), but I thought it was better to just leave everything.

I have to admit, I only tested this with one user, so you may want to try it out on a test site first. I am pretty sure that the usergroup, join date, and post conditions work right, I just don't know what would happen if there were many users to delete. I didn't know how many could be done in a batch so I wrote it to do batches of 50, but I didn't test that feature.
