This allows it to be translated into Flemish.
The code is based on the code for l10n_ch.
Note that the post install hook 'l10n_be_wizard.yml' has
been replaced with a python hook in 'wizard/account_wizard.py'.
This was done because the yml based hook runs before the
actual translations are loaded and hence fails to
properly translate the chart of accounts.
Lastly, a first, incomplete translation has been included.
