[phobos] Commit Messages for Tools Repo

[Jonathan M Davis]

I just realized that while I receive messages from github for pull requests 
for the tools repo, I don't receive any commit messages for it. The compiler's 
commit messages go to dmd-internals, druntime's commit messages go to d-
runtime, and Phobos' commit messages go to phobos. Is there a list that the 
tools commit messages go to? If there is, apparently I'm not signed up for it. 
If there isn't, I'd suggest that they get sent to the phobos list so that they 
get seen just like the other commit messages.

And now that I think of it, the dlang.org project has the same problem. 
Perhaps its commit messages should be sent to the phobos list as well. Its 
valuable to see when commits are made and what they are.
