Website Changes

["John D. Ament" <jo...@apache.org>]

All,

I was able to get a hold of infra about the website build automation.  A
couple of changes went in (or are going in shortly):

- There is no more master branch, instead all work should be on the
asf-site branch
- The buildbot config is checked in on our side but is not the source of
truth.  A copy resides in infra's svn repo.  If you make changes to this,
please raise an infra ticket to alert.
- The content directory is unignored, changes will be tracked.

John
