Monospaced BBCode Editor

A userscript for Empornium that sets the font family of the BBCode editor to a monospaced one.

This script should help legibility when writing BBCode, as the default font is a sans-serif one. For writing code like BBCode, a monospaced font is generally preferred.

The "font-stack" used is the the same as the one used by a popular CSS framework:

1. ui-monospace
2. SFMono-Regular
3. Menlo
4. Monaco
5. Consolas
6. Liberation Mono
7. Courier New
8. monospace (a fallback "web-safe" font that will always be available)

This script targets any <textarea> on ths site, so it may affect ones beyond BBCode editors (which are unfortunately not marked up in any easily-identifiable way), but that seems like a good thing.
