Render the inspector into the sidebar

#### To QA
- Use the `il` flag.
- There should be no search bar in the charm list.
- Drag a charm to the canvas and the inspector should open in the sidebar.
- Deploy the charm then click on the icon. The inspector should open in the sidebar.

#### Notes
This branch is missing some tests because they will be thrown away anyways as soon as the change state code is implemented.
