Q4M 0.8.5 released

Q4M 0.8.5 is now downloadable from q4m.31tools.com. Prebuilt binaries for MySQL 5.1.33 running on linux (i386 or x86_64) and Mac OS X 10.5 (x86) are available as well.

There are no bugfixes in this release. The only change from version 0.8.4 is bundle of boost header files necessary for building Q4M. The build process no more requires separate installation of the Boost C++ libraries.
