Created scaffold for moving the inspector instantiation code into browser.js
Ghost inspector deploys the charm and navigates the the new inspector url
Added test for rendering the inspector into the sidebar
Merge pull request #204 from hatched/prep-charmbrowser

#### 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.
