Utilize max bolus limit in Bolus module

In the bolus module, if bolus amount is set over the `Max Bolus` set in `Pump Settings', disable the `Enact bolus` button, change it's text to `Max Bolus exceeded!`, and change alert dialog for external insulin.

If bolus amount is set over 3x Max Bolus, disable the external insulin button as well.

Cherry-picked from https://github.com/Artificial-Pancreas/iAPS/commit/581e3e2838f7ee461df8f86c17db06450d49850e and https://github.com/Artificial-Pancreas/iAPS/commit/7c7cafecf2c10b377d329559b851e417c02ebe96 but had to refactor the alert to get it to build
