Create a single transmitter for Diagnose
Diagnose script performs two external HTTP calls, one for push api key validation, and another one to send the diagnose results to AppSignal if the user wants. These calls were written separatedly inside the diagnose script, now they are done through a new class called `Transmitter`.
