Nightly builds for Z3

We are now providing Z3 nightly builds for all major platforms (Windows, OSX, Linux and FreeBSD). Christoph Wintersteiger and I implemented a new infrastructure that automatically builds and tests Z3 every night. If it passes the tests, we upload the compiled binaries to codeplex. This feature is useful for users that found bugs, and do not want to wait the next official release. So far, these users would have to download the source code from the "work-in-progress" branch and build Z3 themselves. Note that these nightly builds are not official releases. They are built using the "work-in-progress" branch, but our infrastructure only uploads them if they pass the basic set of regression tests we have. Since they are not official releases, we include the git hash associated with the commit we used to build the binaries. That is why the zip files have funny names such as The value 5e72cf0123f6 is the first 12 digits of the git hash. The hash is also embedded in the z3 executable. We can retrieve it by executing z3 -h. Users using nightly builds should include this hash when reporting bugs and/or problems. Given a hash such as 5e72cf0123f6, we can use the command git checkout 5e72cf0123f6 to retrieve the source code.

Here are the instructions for downloading a nightly build
