    ide-list-files: add test utility to list project files
    
    A series of "ide-*" tools will be added that we can use to test the
    libide implementation. Longer term, they might be useful outside of
    building Builder, but no plans on that at the moment. Therefore, they
    are noinst_PROGRAMS.
