HWI: propagate error messages all the way up to user interface

Abhi,

From memory the CLI handles that by sending the output to SessionState.err. We also might be able to collect the last exception and store it. We left a hook open to write the error stream to a separate file. Open up a Jira, and we can talk about the best way to implement it.

Thank you,
Edward
