[OK] Google Contacts Import, AddressBook backend Contact App

[monsieurh]

Purpose

• Add a program to convert google exported contacts to an agnostic format.
• Presents a basic architecture for storing Contacts in ZPUI

Implementation

• python package vobject is used to parse vcard format (may be compatible with more than just google, untested)
• Contact class contains all data for a contact. All attributes are lists to stay compatible with vcard standard and allow future exports. Contact,merge(self, other) and Contact.match(other) are worth noting. They allow repectively to merge two contacts into one and to compare how similar they are.
• AddressBook is a python Singleton that loads, saves and organizes contacts. AddressBook.search and AddressBook.find_duplicates may be used in external applications

Discussion The storage format is a pickle.dump of the list of contacts

1. the save file is stored in $XDG_DATA_HOME. If not available ~/.zpui/ is chosen (Thanks to @bjoernfan on irc for the suggestion). Do we keep it that way ?
2. The save file is unencrypted and dead-easy to read, what should we do about it ?

Changes implemented

• default fallback save folder is now ~/.phone
• split AddressBook and Contact class in separate files
• moves flatter() in helpers.general
• adds an application to browse contact (personal/contacts)
