DLL registering

[Chipp Walters]

Hi Eric,

In order to use a DLL with RunRev there are a couple of things to know:

1) The DLL must be compiled specifically for RunRev; IOW, you can't just 
use any DLL with RR.

2) You don't need to register it. Just put it in the folder with the 
.exe and set the externals properly.

best,

Chipp
