Source/devtools/OWNERS, your rubber-stamping power is required!

Changed also some additional symbols in the StyleBuilder.

Hi Julien, 

I had to post a new patchset because of some symbols I forgot to rename. Could
you please take a look to the new patch ? Thanks.

lgtm, I don't need to see any updated patch.

Let's improve your change description before landing this though. We like to
follow the commit log message for easier reading (couldn't find an official link
but following
overflow.com/questions/2290016/git-commit-messages-50-72-formatting seems to
match what we do). For this change, here would be my take:

Rename grid-definition-{columns|rows} to match the new syntax

In the latest WD, grid-definition-{columns|rows} were renamed
to grid-template-{columns|rows}.
