provide better deleting options

there should be a way to delete more than one message. manually deleting one message at a time can be a hassle when there's more than one message you wish to delete. in addition, there should be an option to delete all messages you sent in one dm at once. 

this has been asked for a lot too in feedback, yet theres been no change lol. anytime you youtube 'how to delete more than one message on discord' they're basically giving you instructions on how to 'hack into discord', which can be risky on it's own since most of it is against discord's TOS or whatever and can make your account locked thus no longer giving you access to your own account anymore.
