[Users] Changing the prefix in subject for mailing lists

[Bogdan-Andrei Iancu]

Hi,

there were couple of requests to change the prefix used by the mailing 
list to something more descriptive. Like:
    [Devel] -> [OpenSER-Devel]
    [Users] -> [OpenSER-Users]

I guess it is quite standard to have the project name included in the 
prefix, but I want to see if anybody is aware of an side effect ;)

regards,
bogdan
