[Koha-translate] String freeze - Updated strings

Hi all, we are in string freeze, there are updated strings for Koha 3.16, 3.14 and 3.12 As always concentrate first on the last version (3.16), and first of all fix errors (XMLtags and printf). Later I can use 3.16 strings on 3.14 and 3.12, as already done for Italian and Slovak :) Best regards, Bernardo -- Bernardo Gonzalez Kriegel bgkriegel@gmail.com
