Dexed, revived!

Thanks to someone who commented on this Reddit thread I made 
about it:

I was able to track down a full copy of almost-the-latest-version 
of the Dexed repo (version 3.7.4) and have put it up here:

No binary downloads available yet, but I'll try to get them up 
for at least the platforms they were originally available ASAP 
(and perhaps, eventually for Mac, as the Cocoa backend for 
Lazarus is pretty mature at this point.)

There's a few obvious (to me at least) bugs with regards to the 
window docking system that I intend to fix first, though (as well 
as a few other things that strike me as having clear room for 
improvement.)
