Configuration for project directory structure

[LABBsoft]

Configuration for projects/ folder with pxt serve

Problem: pxt serve only searches for projects in the projects/ folder and subdirectories no more two layers deep

I'd like the ability to choose how to organize my local project structure.

Possible solutions:
Argument to add directories for pxt serve to target.
Increase the maximum depth of the pxt serve project scan (2 is just too limiting)
