[v1.4.1] Fixed and improved quotes

• Fixed a bug with /save and /quotes where recently saved quotes weren't showing in the menu
• Added the ability to save voice messages [beta]
• All users are now mentioned in the quotes, even if they don't have a username (apart from anonymous quotes, they still remain anonymous)
• Removed the Delete All option as it was causing some users to delete all of their quotes by accident when the keyboard moves upon new messages being sent
• Added /s as an alias to /save, and /q as an alias to /q
