Configure URL's

We still have two hardcoded URL's in our project, the ThingSpeak URL and the IFTTT URL. In order to make these configurable we'll use parameters in the WiFiManager project. The user can then provide these URL's when they are connecting to their own WiFi. Read the provided Random Nerd WiFiManager Tutorial to get started!

Set the provided URL's to a global variable and save them using the Preferences library for the next boot! (See the sensor calibration exercise for a refresher).
