Add an option in Admin Panel to modify entrance file size limit and duration

[lynxcool]

Problem

Currently in the admin panel, it's possible change limits for various features, but it's currently missing for entrance sounds. It can only be toggled on or off.

Proposal

Add an option to modify how large the entrance file is allowed to be and how long it's allowed to play.
