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).
seems like
``` clojure
(defn safe-enable-console-print! []
  (when (or (not agent/IE)
            (agent/isVersionOrHigher 9))
     (enable-console-print!))
```
might be a useful util fn?
