* adds NewEcoAccountForm
* refactors NewCompensationForm into AbstractCompensationForm so main fields can be reused again
* fixes template bug in account detail view where the amount of deductions has been displayed instead of the available rest
* refactors _generate_new_identifier() into generate_new_identifier()
* refactors get_available_rest() into returning both, the total and relative amount
* improves saving of SimpleGeometryForm()
* adds/updates translations
