Move DeviceType to its own file, add helper and constants. Make a device_type.go file, to avoid a mess in the devices.go file. Move the DeviceType definition over to the new file. Also, while we're here, set up a few of the contstants we know we'll need. These are the DeviceTypes we intend to support, such as Android phones, Android tablets, and Chrome extensions. Also, set up a helper method that will determine whether a DeviceType is "valid", i.e. if we have a constant defined for it. DeviceTypes, in general, are mostly intended to be used (at the moment, at least) to customise how we display devices to users. Basically, they allow us to display an at least semi-accurate depiction of the device.
