Build up correct path to default settings

The assumption has been that the application will be started in the
root of the repository, and uses that to source the default
settings. It is, however, possible that the application is started in
a totally different working directory, which leads to an error during
startup.

This commit sources the default settings relative to a know file, in
this case the module __init__.py file for qc_app module.
