UI hang on missing config.py

[spyysalo]

If config.py is not present, appropriate error messages ("Missing file config.py ...") are shown, but the UI hangs. May be due to failure to deal with client-server exception configurationError.

Seems other client-server exceptions can result in this state also.

UI should hang if the configuration file is not present. The only thing that the client should do in this situation is inform the user they should go yell at the admin. What else would you expect? The only complaint I have in this scenario is that the client does not die soon enough, spamming the message three times, and that the server returns the exception without copying the action value in the response which results in further spam.

Ah, I did not pull. Still, should die sooner. On it.

@amadanmath : not doing anything is fine, but blocking the user from either reloading the page from the KB or from seeing the messages from the server (i.e. disabling mouseover on the "info") is not.
