Require users to specify a page number for the `case list` command

[StrangeRanger]

Is your feature request related to a problem? Please describe. If there are a lot of cases in the current server and the command ?!case list is used, it will print out every single case, which takes a long time and spams the channel that the command was used in.

Describe the feature you'd like in detail When using ?!case list, instead of printing every single case, require the user to specify a page number that they'd like to view, and if no page number is provided, default to page one. This will help prevent the flooding of a channel.

It would need some additions to the footer, so you can see which page you are on and how many are left
