Instead of using the default release message and then trying to fix it up
in the after_success section of one of the builds that we test, let's just
always use the message that we want, regardless which build finishes first.
This currently requires my fork of the uploadtool - the changes have been
submitted upstream and I hope they'll get merged there so we can switch
back to the upstream version of uploadtool.

In the process, simplify our dependency a bit by no longer building
against libssh2 (we don't support ssh based authentication for git
on Windows) and libcurl (since it's proxy implementation doesn't appear
to actually work on Windows, anyway).
