Adds clean make target
Adds prior closed merge for assuming charm-helpers-sync is not a global bin
adds me to the maintainers list
i just... i hate path munging. the only way we're going to make that happen is if we add a setup.py to the charm_root. does that sound any more sane than what putting it in hooks/ does? Because if thats the route you want to take. I'll do that for the next iteration of the PR (which sorry i opened this way early... i've got at least another 10 changes coming)
