The new feature makes it possible to create analytic codes for historical
data from the web interface.

Main changes are :
- Change fields declaration
- Update metaclass to add field to nmspc instead of _columns
- Add v8's version of compute/reverse/search function of
    disable_per_company field

Also remove data in account_numergy

The MetaAnalytic metaclass can now be used to bind a dimension to a model, generating a new code for each new record.

The README has been updated with more instructions.

Fields generated by MetaAnalytic now exclude codes with children. Fixed some issues when selecting the parent and dimension of a new analytic code. Added a new 'translate' option.

When creating a code, the parent cannot be selected (readonly) if the code's dimension is not selected (code view) or not a record in the database (dimension view, while creating a new dimension).

Added descriptions to models. Added a 'translate' option to enable/disable translation of analytic code and dimension names (default: False). Fields generated by the metaclasses now have a common placeholder string value. Cleaned up the translation file.

The number of analytic fields can be defined in the OpenERP configuration file, category [analytic], key analytic_size (default: 5).

The default behavior is unchanged.

Analytic scructures can now use different ordering values for the same dimension. Models that use analytic code fields should now use conditions on nd_id.ns{n}_id.model_name in the domain for those fields.

Added a parent-child hierarchy on analytic codes. Fixed a bug where analytic codes without a description couldn't be selected.
