organize a little the code

[Francisco Rojas <frojas alumnos utalca cl>]

I propose organize a Little the code, so my idea is make a few class to
separate the code from ui.

the class are: 

-GyrusAcl: basic ist put gyrus_acl.py  into a class and take out all
related with UI.

-GyrusMailBox: Contains all data related to this, like a list of acl and
list Subdirectories

-GyrusMailBoxAdmin: i'm sure about the name, but the idea is it contain
a list of Mailbox and all the data to connect with the server.

What do you think?
