Get a patch and I can make dubautotester run on it to see what breaks.

I originally intended to use it to determine which patches we could safely 
backport in order to construct more stable DMDFE versions without vastly 
increasing the amount of human work. Like, we get a patch against master; 
try to apply it against 2.080.1 and see if it (a) still works (b) compiles 
everything that 2.080.1 did (c) doesn't compile anything that 2.080.1 
didn't.

Automatically apply it to the next patch version if all that passes. 
Automatically apply the patch to the next minor version if only (c) fails. 
Make a report for human intervention. Or something like that. The main 
issue is that it takes a *lot* of time to run these tests, so more than 
one patch per day would require me to set up parallelism and upgrade the 
build box.

Evaluating the effects of a proposal like this is pretty similar.
