Horizontal rule markdown support

[bizojs]

Current problem

Currently there's no real way to naturally separate markdown content without workarounds such as using custom separator emotes

Proposed change

I would like to see Fluxer support parsing horizontal rules

Additional information

Some mockups of what this could visually look like:

This would be great for all sorts of uses, and the syntax presented in the markdownguide link seems about right. Save for one minor thing, that is: Fluxer prunes empty lines at the beginning and ends of messages. This would prevent the horizontal rule's use to begin or end a message, which is something I can see people wanting to do. Maybe foregoing the empty spaces as a requirement would help.

With respect to the mockup though it looks borderline invisible and in practice would perhaps benefit from being brighter or thicker.
I hope this ends up added in some form, either way!

Good points, i don't think Fluxer prunes empty lines if they're part of the content, but yes this could be a concern if you were sending a horizontal rule as a separate message

The colour in the mockup I agree is quite hard to see, it was more of a "mockup" from within Fluxer using inspect element, so I just stole the separator used to indicate a message was sent in a different day :P

Appreciate the feedback regardless!
