Crosspost between channels feature

[samhwang]

Is your feature request related to a problem? Please describe.
Crossposting in our Discord channel is now becoming a thing in our Discord server because people keep on derailing things (me included) sigh

Describe the solution you'd like
When a message with the keyword cross-post crosspost or xpost appears, this can then be parsed, find the mentioned channel name, and copy the URL to said post into the mentioned channel.

Example flow:

• cross-post #meme-and-shitposting <content> <image> message is sent into the #general channel
• Bot will detect the keyword cross-post and post the URL to the message in #general into the #meme-and-shitposting channel.

Let's be explicit about the command and not rely on too many keywords. We are IT professionals here. :)

My proposal for the solutions:

1. User reply to a post they want to crosspost.
2. Then user type /crosspost #meme-and-shitposting.

Just realized that DiscordJS has some functionality regarding crossposting channels while I was working on #82 . Maybe it can be utilized.

We can't use the bot's slash command when replying to a message
