commit deb5d6a1e95e8f0a6ba97e37d17163d37e531729

Fail build if triggering fails

Introduce the concept of "fatal error" to AnnotatedCommand. In case of
fatal errors, mark entire build as EXCEPTION and put the details in the
fatal_errors log of the preamble.

If 'critical' is True or absent in a triggering spec and triggering
fails on the master side, it is a fatal error.
