added debug logging message for detected devices.

adding a mocked class for Config.
Adding device type to Device struct. Will eventually be needed for raid drives.
adding End-to-end testing capabilties.
Added testdata json files for webserver requests.
Seperated Start code and Setup code in webapp so we can test.
renamed "smart_attributes" to "ata_attributes" - Backwards incomatible change.
Added front end device sorting (red, yellow, green)
show unknown icon/status if drive has no smart data yet.
Moved all attribute "getters" into the controller.
