Package version use needs to be fixed #214
Description
Currently the location where the dragonfly version is accessed and used is not correct, nor is the way that it's used, meaning that we don't get dragonfly information in DL messages.
Currently it's accessed in dragonfly/dripline/extensions/jitter/__init__.py. It needs to be in dragonfly/dripline/extensions/__init__.py.
Furthermore, it's not stored in dl/core with core.add_version() as is done in dripline/dripline/__init__.py.
At the same time, prints should be switched to logging. The exception catching should be kept.
