Update the machine tokens instead of rerending the entire machine view.
Fixing initial inspectors on deploy.
Merge pull request #284 from makyo/initial-inspector

To QA:

With the il flag, drag and drop a service onto the canvas; the inspector should open.
Inverted the machine add method to allow us to use the YUI event system as intended
Merge pull request #285 from hatched/machine-view-render-changes

Original PR: https://github.com/juju/juju-gui/pull/280

Machine tokens should be updated instead of re-rendering the entire machine view on every machine model change.
Apply final machine view rendering fixes from bad rebase.
Show add relation menu even if we're on the il flag.
Merge pull request #287 from huwshimi/fix-build-relation-popup

The build relation menu is still required when we're using the il flag, but we don't want to shrink or expand the inspector.

QA:
Deploy mysql and wordpress.
Click on the canvas so that the Build Relation menu disappears.
Now click on a service and the menu should appear again.
Click on the Build Relation menu and you should be able to create a relation between the two services.
Merge pull request #286 from huwshimi/fix-rebase

This is the final set of changes meant to be in the machine view rendering branch that got lost in a bad rebase.

This branch adds missing code comments and also sets the header labels through the widget setLabel rather than poking at the DOM. This required refactoring how we set up the headers so we can access them directly.

QA:
Add or remove some machines and the machine count in the header should update correctly.
Selecting a machine should set the container count correctly in the container header.
