Fix: Restore usage of text field for "enabled" menu because, even if in
standard code, we use 0 or 1, into external module, or menu editor we
should be able to use full condition dynamic string.
add localtax1_type and localtax2_type in database.
these type are char(1) and support following values :
'0' : local tax not applied
'1' : local tax apply on products and services without vat (vat is not applied on local tax)
'2' : local tax apply on products and services before vat (vat is calculated on amount + localtax)
'3' : local tax apply on products without vat (vat is not applied on local tax)
'4' : local tax apply on products before vat (vat is calculated on amount + localtax)
'5' : local tax apply on services without vat (vat is not applied on local tax)
'6' : local tax apply on services before vat (vat is calculated on amount + localtax)
'7' : local tax is a fix amount applied on global invoice
