new Bro release available - 0.7a175

A new Bro alpha release is now available from:

  ftp://ftp.ee.lbl.gov/.vp-bro-pub-0.7a175.tar.gz

It includes a considerable number of changes and new features (some quite
experimental and likely to change somewhat in the near future). I've
appended the relevant entries from the CHANGES file.
