check that library has been versioned greater than last successful deployment

[elduddz]

For a build to be successful, it should be a version greater than the last full release.

builds from a branch other than master will happily create pre-release versions of the package that is effectively already released.

I am thinking some sort of check against the gallery and checking the module release version vs the version in the branch.

not sure what happens when all you change is the readme
