Allow invoice subclasses to explicitly declare their exported columns…

… and column names

Two class attributes, `export_columns_list` and `exported_columns_map`,
has been added to `Invoice`, along with a class function `_filter_columns()`.
Subclasses of `Invoice` must now define `export_columns_list`, containing
the ordered list of columns that must be exported in their respective
invoices. Subclasses can optional define `exported_columns_map`,
containing mappings between "internal" column names and what their
name should be when exported.

The field name `RATE_FIELD` has been added to `invoice.py`. It was
previously forgotten.
