[HEADSUP] preparations for ports release for 7.0

This is a pointer to the headsup I posted to freebsd-ports_at_ detailing the
switch of portsmon's default build environment from i386-6 to i386-7.
This controls such things as determination of whether a port is marked
"broken" (e.g. with gcc4.2.)

The first set of email reminders based on this have already gone out to
maintainers.  Not too many ports remain to be fixed with gcc4.2, but some
do.  If you are interested in helping out, please take a look at the
following:

http://docs.freebsd.org/cgi/getmsg.cgi?fetch=341967+0+archive/2007/freebsd-ports/20071014.freebsd-ports

It also details some new graphs that allow you to see the visual comparison
of how well the package builds are doing on each build environment, and
also to drill down to a pie chart for each build environment, and a complete
list of all ports that do not package for one reason or another for each
build environment.

If you're considering upgrading to 7.0, or even want to see the comparison
between e.g. i386 and amd64, I think you will find this information useful.

Note: the reports are still in the alpha state, so you don't need to report
bugs to me: I am well aware of them :-/
