Merge pull request #145 from hatched/upgrade-or-new-inspector

__Notes__
This is a partially incomplete branch. To continue I need to convert a viewlet to view which is out of scope of this branch so I am landing this in the interm.

__To QA __
- Deploy a local charm
- Try and deploy the same one, a small black box should appear with the text "Local Charm Upgrade"
Converted the requestSeries viewlet into a viewlet view
Removed tests which are no longer valid in the local-charm-import-helper.
Added tests for the new request series view and cleaned up some of
the request series viewlet manager instantition code.
