Updating build script to name packages after git tags. If tags don't exist, pull from the build.properties.
Had issues with the jar names with tags.
Merge branch 'master' of github.com:azkaban/azkaban2 into release-2.5
Build packages now adds azkaban.versions file to determine which version of azkaban is built.
Convered git tag command to git describe to get the current tag instead of all of them
Added abbrev=0 to the git describe command to just get latest git tag.
Last commit only picked up the first tag, instead of the current one. This one does the right thing.
