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).
It is used further down. I'm not sure why it is capitalised either, but it was like that when I found it and I'm a bit nervous about changing too much code here.
