Added machine, container and unit removed states in the machine view

Display the removed states for machines containers and units in the machine view. These are not currently visible and will be hooked up once the ecs flags machines, containers and units as deleted.
It was actually never checking the uncommitted state, it would always return that symbol as well, I figured it was more sensible to just test the title part (I had modified this in an earlier branch, and this is probably the approach I should have taken then).
