Don't swallow namespace-parsing errors

Previously, if there was a problem with the inputs and bild failed to
determine the namespace, 'fromPath' would return 'Nothing' and then
'catMaybes' would drop the error-causing input altogether. In the one
time that I had a bad input, this made debugging incredibly difficult.
It's always a bad idea to swallow errors silently, so instead lets just
kill the program if we have bad inputs.
