To make contributing to /s/Threads easier I added a new syntax that makes inline images easier.

Previously the way to do this was to use the standard syntax from extended markdown. This with no spaces ! [] (url).

We now also have ! IMG url. Just take out the space after the exclamation. I'm avoiding triggering it. Or just do this in all-caps.

!img someurl

The last nice thing is that both methods now wrap the image in a link.
