Make this work more similar to other BBCode for editing uniformity

This is just a casual suggestion, but since this is so similar to BBCode style already, why not take it all the way to fit in better with that editing paradigm? I'd suggest a typical structure for input like this, similar to the BBCode img tag:

Rather than the current system, which obeys no convention I'm aware of (which doesn't say much, I'll be honest).

I am modifying the module for my own project and was able change it to the proposed stucture pretty easily.
