Suggestion : make treatments always selectable

[JohanDegraeve]

Is it possible to make treatments always selectable, also if there's no readings or calibrations yet ?

One user here in Belgium wants to use the carbohydrate counter but doesn't have a transmitter.

I think the change to be done is here : https://github.com/SpikeApp/Spike/blob/master/src/ui/screens/display/treatments/TreatmentsList.as#L75 Remove the property canAddTreatments and also the code where assignment is done, and where it's used use value true.

Probably also canSeeTreatments

Sorry I can't compile right now, I couldn't make a pull request
