Limit the amount of topics per user in a specific category

Small update:
Changed the 5 minutes auto-deletion timer to be 24 hours instead, 5 minutes was nice for keeping the forums clean quickly, but it was too quick for most users to realize what was happening or to even “appeal” the auto-closing of the topic before it got deleted. 24 hours gives staff and users enough time to cancel the deletion if there is a need for that.
