Revision ec96c0b3c2
attempt to display the VAT label according to the country
vat label.
This a very commendable effort, except that the
`vat_label` was not available under the variable
`company.country_id.vat_label`
Actually even `company.country_id` was undefined.
This revision does what it must be done in order
to read the countries `vat_label` and to make
it available through a variable for the bill receipt.
