Prefix non-datatype properties and methods with $

[gmaclennan]

Our initial intention with the API was to prefix all properties and methods that are not datatypes with $. The reason for this was to remove the possibility of a naming conflict between a datatype name and a property or method on the API. We have forgotten about this with some of our naming:

• project.deviceId
• project.importConfig()
• project.ready()
• project.close()

I think the original intention and reasoning was valid, so I think we should rename these properties and methods. This will be a breaking change for the API, but should be easy to manage because we ship the API with the app. This is non-urgent, but I think worth addressing at some point.
