Local inspectors properly display in sidebar

Set the correct wrapping elements on the local charm inspectors so they display in the sidebar correctly.

QA:
- drop a zip of a charm onto the canvas
- check that the inspector that appears is the full height of the sidebar with the buttons at the bottom
- click "Upload"
- drop the same zip on the canvas again
- check that the new inspector that appears is the full height of the sidebar with the buttons at the bottom
Disable the deploy button if there are no changes.
Clean the delegated closing method up so it doesn't break the details on subsequent clicks.
Change export to bundle.yaml, not export.yaml.

Merge pull request #383 from huwshimi/deploy-button-disabling

Disable the deploy button if there are no changes.

The deploy button should be disabled when there is nothing to deploy.

QA:
- load the gui with the mv flag
- check that the deploy button is grey and that clicking on it does nothing
- drag a charm to the canvas
- the deploy button should be orange and clicking on it should open the summary panel
