Feature: Extensions persist across projects

micro:bit support 27103

Issue:
When attempting to program the micro:bit, it is often necessary to download an extension to include features of a particular environment.

Examples: SparkFun's "moto:bit" or Dexter Industries "gigglebot"
These two hardware platforms require these extensions.

What I observed:
When programming a device, I download a particular extension. If I want to start a new project, I hit "new project" from the home page and a new project is created, but without the extension(s) loaded.

In the case of teaching my granddaughters how to program using MakeCode, I entered a simple program for them as an example, let them play with it, and then had them "start a new project" to create a program of their own. Alas! the downloaded "Gigglebot" extension was missing and caused no end of confusion.

Feature Request
Allow downloaded extensions to remain when creating a "new project" (this could be a "setting") This would allow the student to create new projects at will without having to search and download the necessary extensions each time.
