Add “About” modal that displays /v2/info data

* The endpoint is polled when the modal is opened and then not again
* Modal can be opened with “shift+,” (to mimic OS X’s command+, for
  opening app preferences)
Remove padding-bottom on nav for border-bottom

Removing padding-top pulled the text up rather than keep it in place.
Add keyboard shortcuts to move to “apps” and “deployments”

* “g a”: go to apps
* “g d”: go to deployments
Remove console statement, strictly
Add JSHint exceptions, strictify
Allow undefined in ObjectDlComp since data is async
Color `<code>` to blend with `<dl>`
Use h5 to match app modal headers
Specify padding-top as required by app modal
