Builds can now be found in the Jenkins workspace

[Kevin Minder]

Hi Everyone,
After reworking how the build was done you can now find the builds in 
the Jenkins workspace after a successful build
https://builds.apache.org/job/Knox-master/ws/target/
Note: I'm currently generating hashes (SHA1 and MD5) as part of the 
build.  I'm not sure if doing so is necessarily appropriate.  The 
signing and staging of a release still needs to be handled as a separate 
interactive step as it requires input from the signer/stager.
Kevin.
