In order to clearly separate app data from statically served files it will
be useful to have 2 directories under /var/www/trac, one named "instance"
with all the instances and one named "htdocs" or "html" with the static
files.

Until recently /var/www/trac was the DocumentRoot for trac.osgeo.org and
this opened up access to a lot of not-intended-for-public-eyes files.

Now the DocumentRoot for static files was moved (by myself) to
/osgeo/trac/htdocs, while /var/www/trac remained for the instances.

I hadn't moved the instances because I was concerned about the backup
procedure, which (I've been told from Martin) uses trac-admin and
references instances via "/var/www/trac/<instancename>"
