Frontend review process suggestion

[janderson]

Whenever something changes in the source code at work we get an email 
detailing the file changes.  This encourages a form of code review 
because it encourages others to check my changes.  I could always go to 
perforce to do this but that is not right in my face all the time.

Since the DMD frontend is open source I was thinking that it would be 
cool if the DMD changelog included a diff of the changed frontend files 
since the last one.  Users could click on a link and see what changes 
where made.  How this would look I don't know.  I don't even know how 
you'd set this up.  I know there's some tools out there that can spit 
out HTML diffs.

Also if you like this idea, what would be a practical way for Walter to 
set this up.
