Bug 1494543 - Part 2: Add model + short runtime name to the sidebar item. r=jdescottes,daisuke Added new getters to the ADB scanner so our runtime objects have now the information we need. Note that the UX of the devices in this patch doesn't still match what we had in the mockups (icons don't match, and we also need a circle with a tick), but since we have another bug to handle the CSS in the Sidebar, we can always adapt it there. The information needed to display what is shown in the mockups should be passed in this patch –if I miss anything, give me a shout!
