Here is the beta of the DLL. The final version will have any bugs you guys find fixed and some other internal stuff fixed that works with the new yet to be released editor.
The dll will look for mods in any folders created in the root of the game dirs, it must have a mod.ini in there that looks like this:
[mod]
name=My awesome mod
description=Kill sligs and things
These will then appear in the drop down list in the UI.
Edit: Ran this run all AV scanners at Jotti, one scanner dosen't like it because it uses UPX:

If you use that AV I'd suggest you get a new one since a packed binary could result in you being hacked, winner for an AV :P
