Poor handling of situations with multiple popups

[SystemlessDev]

In this situation the user gets both a friend request and a party request. PopupEvents will display these at the same time (over each other) and try to accept both. The server in question would deny you from accepting the party in this case due to typing commands too fast.

A solution for this would be to implement a queue system.
As in first display the friend request and wait for the user to decide. After it has either timed out or the user has accepted, display the party request.

You can use an ArrayDeque for this - every time a popup is consumed, display the next one.
