Fix the left inspector to fill the height of the sidebar.
Merge pull request #219 from huwshimi/left-inspector-full-height

Fix the left inspector to fill the height of the sidebar. I've tested the use of flexbox across our browser matrix.

This no longer needs the resize calculations as flexbox is smart enough to handle the adjustments we were making.

We need to fix the nested footer controls, but I couldn't figure out a smart way of doing that.
List machines in the machine view.
Lint fixes.
Merge pull request #222 from kadams54/mv-list

To QA:

You'll need to use the `/:flags:/il/mv/` feature flags. The machine view will come up in an empty state. Deploy a charm and verify that the machine view has been updated appropriately, both in the list and in the header ("X machines"). Destroy the service and verify that the list still looks good.
