Follow-ups to #553. Closes #598.

• feminine numbers before hora and libra (2 h reads duas horas, £200 reads duzentas libras), including times (1:30, 22:15)
• signs are spoken or dropped instead of left behind (-1 h, -0,5, +R$ 5)
• % reads por cento
• currency: exact millions take de (um milhão de reais), $1.50 keeps its currency word, malformed amounts (R$ 12,505) fall through to the number pass
• long decimals keep their digits, huge hour counts are left as digits instead of raising
• units no longer eat clocks or identifiers (12:30h, abc2h)
• h-notation times read (12h30, 2h30min, 14h), and a time with letters glued on is left alone (12:30abc)
• hours read without the units option (14h, 2 h), same as 14:30. other units stay opt-in

Extends the Portuguese flood test to unit and time patterns; updates adding-normalizer skill with the testing and gotchas (pass order, num2words limits, etc).
