[ADD] l10n_fr_fec_import: added a module for import data from FEC

A FEC file (Fichier des Ecritures Comptables) contains all the accounting data and entries recorded
in all the accounting journals for a financial year. In order to make the onboarding of new users
easier, Odoo Enterprise's French fiscal localization includes access to the ``l10n_fr_fec_import``
module, that enables the import of existing FEC files from older software to the Odoo database.

The imported data are:

    * accounts
    * journals
    * partners
    * journal entries

Every entity is imported with a generator that reads the values from each line, ready to be loaded.
The entity (only accounts for the moment) is then completed with data from the CoA's templates
and imported in the database. Journal entries are posted and reconciled.

The Odoo branch implements the install checkbox in the Settings > Accounting page for an easy install.
