• Removed command cooldowns since slash commands already have built-in rate limiting
• Removed check for bot user executing a slash command as it isn't even possible
• Pressing command buttons will now keep editing the same message for a smoother user experience
• Fixed command reply sources showing as "Original message was deleted" after pressing a button
• Fixed pressing buttons erroring in channels where Maunz was missing other permissions
• Fixed some core command/button code not having its errors handled and causing infinite "Maunz is thinking" on error
• Moved command/button exception handling to a shared method
• Added editReply Util methods so components and embeds will always be reset without needing long lines of code, necessary now due to the always editing same message change
• Reduced number of Util msg method declarations as they are rarely used now with legacy commands gone
• Added a check for missing permissions in the provided /services add tracking channel
• Limited dynamic button labels to 80 characters (Discord limit) to fix errors in cases such as server selection with long server names
