[Phone Server dbus API]: methods vs. signals

Thanks for all your mails on that subject.

Now that I understand that due to the inherent asynchronous nature of dbus, 
it's actually merely a matter of how the application choses to use the API.
Which makes me confident my first API draft is actually not too bad.

Two followup questions on that though: Since both methods and signals can be 
called asynchronously, when should we broadcast and when not. Right now I 
have chosen signals for status changes that potentially could be interesting 
to multiple applications. I did not use signals for returning phone book 
entries or SMSes (although the arrival notification is of course a signal) -- 
I tend to think broadcasting these results is over the top -- what do you 

Marcel, if you have a chance, I'd appreciate if you could take a look at the 
complete API as it stands in svn and comment on that.
