[DISCORD] Make checkowner and listuser commands available to those who aren't VIP

[lb]

Currently only VIP's are able to use channel commands (ch cr v, ch del v etc.), these include both the checkowner and listuser commands. Only VIP's are able to create temporary text and voice channels so the commands for managing channels should only be available to VIP's, however, checkowner is used to check who owns a temporary channel and the listuser command is used to list all players with permissions to this temporary channel. Since both of these commands aren't used to manage a channel they should be made available to all players not just VIP's, so those without VIP can learn information about the channel should they wish to join / know who has permission to join it.
