Unnecessary noise on missing config.py

[spyysalo]

When trying to open a new brat without first creating a config.py, the following messages are shown:

Protocol error: ActiongetCollectionInformation returned the results of action undefined
Missing file config.py in the installation dir. If this is a new installation, copy the template file config_template.py to config.py in your installation directory ("cp config_template.py config.py") and edit it to suit your environment.
Protocol error: Actionwhoami returned the results of action undefined
Missing file config.py in the installation dir. If this is a new installation, copy the template file config_template.py to config.py in your installation directory ("cp config_template.py config.py") and edit it to suit your environment.
Protocol error: ActionloadConf returned the results of action undefined
Missing file config.py in the installation dir. If this is a new installation, copy the template file config_template.py to config.py in your installation directory ("cp config_template.py config.py") and edit it to suit your environment.

As the correct message ("Missing file config.py") is included, this isn't a big deal, but as this issue is likely to be frequently encountered on fresh installations, it would be nice if the output were a bit cleaner.

Perhaps we could create a new client-server protocol exception specific to missing configuration and have the client deal with the best way of presenting the info to the user?

62754d4 fixes a few protocol errors, but messages seem to go missing at the moment. Also, opened #719 for the client-side issue of avoiding message duplication.

As of 24e3ad1, the messages are also OK. Remaining bits for this are in #719 and a related issue in #720. Closing this.
