Co-processing script generator plugin should output even if there are no sinks
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Currently the co-processing script generator plugin only outputs a Catalyst script if either there is a proxy writer or views are outputted. Need to change this such that only a warning is popped up if this is the case (but also need to check if live output is also checked before issuing a warning).
