build: Require unreleased version when generating installers

peter-b · peter-b · commit 985f02ccfc33 · 2017-03-01T09:43:02.000Z
Make sure that the build will fail if you try to build a version of
LiveCode that's already been released.  This simply adds a check that
a matching tag isn't already present in the git repository.
