[Feature] Limit on mobs caught per <time>

[Sti-jn]

I would like to be able to limit the number of mobs people catch. Currently, it can more or less be done by charging money for it but that isn't really something limiting for older players which is the group of people I want to restrict the most. Therefore I was hoping you could make it so they can only catch a configurable amount of mobs per a configurable amount of time
