Qbs: Opening a project creates a directory ../foo-build

When I open a qbs project in Qt Creator, a directory <projectdir>/../<projectname>-build is created.

I didn't do a build, and I also wasn't asked if or where this would be created, it just spammed my parent directory.

Either qbs shouldn't dump files when not doing a build, or, if it really needs to dump files, it should do that in some temporary directory where it can do what it wants.
