Project Source Folder

The MPLAB® X Integrated Development Environment (IDE) automatically searches the top level of the project folder to find your project's source files. MPLAB® Harmony projects don't use this convention. It instead keeps your source files separate from the project files in the "src" folder found beside the project folder. We therefore need to add this folder's location to the project.
