Front End Imrovements

Faster switching between properties in a project and among sensors in a project. Flattened sensor hierarchy (see them all at once). Property details and 1st cut of profile data. And the start of sortable tables (for sensors only atm).
I'd like to find a much better way of doing it. This was just to stop the pain with IE8 while we come up with a better solution. I'm not sure how other cljs logging libs might solve it.
