* i18n(pt-br): fix 5 Brazilian Portuguese strings
A subject-verb agreement slip, a hyphenated colour, and three terms
that disagreed with the catalog's own wording.
* i18n(pt-br): call the comb option "Caixas", as its warning does
Keeps the warning's "As caixas de caracteres" and renames the option
from the literal "Pente" to match it.
