Description
Having .qbp for projects and .qbs for products is inconvenient.
These were introduced to distinguish between projects and products on the command line when calling qbs in a subproject's directory.
We would then walk up the source tree and look for the .qbp file and start the build there.
If we really want this behaviour then it can be implemented in another way.
Please remove the .qbp code (but maybe support loading of .qbp files silently).
