work items

[David Cheney]

Hello, 

As the 1.4 milestone page is getting less useful as planning tool I wanted to outline the work items I have assigned myself for this week.

* finish charm audit - deploy every precise charm, report and raise issues for charms that do not deploy properly 
* finish config-set - it is very close
* add remove-unit - needed for charm auditing
* add destroy-service - ditto
* Fix ec2 bug - hard to audit charms if destroy-service stops working after your 10th charm.
