preferences service, a first implementation

Ok, cool! 

> Mickey, can I put the code in the git repository ?

For sure, please check this code into git.freesmartphone.org -- I have already 
setup a repository for it (opreferences.git). Your ssh key should give you 
access.

> == interface "org.freesmartphone.conf" ==

Please use org.freesmartphone.Preferences as the interface and 
org.freesmartphone.preferencesd as bus name.

Please use dbus naming conventions, see our style guide from OTAPI:

Style Guide:
* dbus methods and signals are CamelCased
* Use Get/Set prefixes for accessors (GetServiceCenter, SetServiceCenter)
* Use Verbs for operations (ListProviders, Unlock, SendAuthCode)
* Use similar terms for similar operations (ListProviders, ListCells)

> OK That's it for the moment. I implemented this with python.

That's cool. We will stick with Python until we are 110% satisfied with the 
interface ;)

Good work!
