Merge remote-tracking branch 'pr/203' into develop
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.
Fix the inspector styling to fit in the left-hand-side panel.
Merge pull request #203 from frankban/sandbox-more-machine-info

Also completed the addMachines/destroyMachines delta
stream implementation in the fake backend.

Removed the ambiguity of having a machine_id attribute
in juju-core sandbox.

QA:
- make devel/debug/prod;
- open the JS console;
- add new machines/containers with the following command:
    app.env.addMachines([
      // A new machine with default properties.
      {}, 
      // A new trusty LXC inside a new machine.
      {containerType: 'lxc', series: 'trusty'}, 
      // A new customized machine
      {constraints:{'arch': 'i386', 'cpu-cores': 4, mem: 2000},
       jobs: ['JobHostUnits', 'JobManageEnviron']}
    ]);
- ensure four machines were added, and they contain the expected attributes,
  by running the following: `app.db.machines._items`
- now force the removal of machine 1: also the contained LXC should be
  destroyed: `app.env.destroyMachines(['1'], true);` and then
  `app.db.machines._items` again.
Done, thank you.
