Data source generation - better status reporting

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Generating a client using a data source (or many) from a slow server
2. The generation show a window that says "Please wait..."

What is the expected output? What do you see instead?
A window with a list of all data sources associated with the client, and their 
progress (waiting, downloading / cached, parsing in progress, error / pass / 
okay), with buttons to decide to force the generation if it fail, clear the 
cache of data sources, etc.

Please provide any additional information below.
This feature will require a server status service, and a good refactorisation 
to allow threaded generation.

Change title from "Client generation - better status reporting" to "Data source 
generation - better status reporting".
Since 1.4, the downloads are done in the data sources, not in the clients. The 
generation of a client now takes only a few seconds.
