Hello,

With the switch to git and Gerrit, we should start formatting our commit message. Over the last days, you might have noticed I have amended a few changes in mediawiki/core.git.

Both git and gerrit use the first line of a message as a summary of the commit which is probably more human friendly than a sha1.

In Gerrit it is used when referring to a parent commit and as a subject for email notifications. In git it is very helpful when using `log --oneline` or cherry-picking a commit, or rebasing interactively.

Inspired by various online resources, I have started writing guidelines and even provided some screen captures:

Edits welcome :-D
