Right, this is the simplest MOD in the world, but I thought I'd post it as a MOD in case anyone else would like to add it.
Carsten and ThM told me how to do this, so I've credited them as the authors, I hope that's okay. A big thanks to them both.
This is the first time I have put anything into a MOD, so if anything needs changing, please let me know.
