Portuguese translation request

[maique]

Hi,

I wonder if we could have a Portuguese translation added to the watch ?

I already translated the strings to portuguese. We don't really use the '25 minutes to..', but rather the 'something 35', so the strings also reflect that. Not sure if that's ok with you.
The strings are for Portuguese from Portugal, not the BRazilian variant.

Also changed the US to PT.

const char* const HOURS_EN_PT[] = {
  // AM hours
  "doze",
  "uma",
  "duas",
  "três",
  "quatro",
  "cinco",
  "seis",
  "sete",
  "oito",
  "nove",
  "dez",
  "onze",

  // PM hours
  "doze",
  "uma",
  "duas",
  "três",
  "quatro",
  "cinco",
  "seis",
  "sete",
  "oito",
  "nove",
  "dez",
  "onze"
};

/**
 * The string "$1" will be replaced with the current hour (e.g., "three"
 * at 3:45).  The string "$2" will be replaced with the *next* hour
 * (e.g., "four" at 3:45).
 *
 * A "*" character before a word makes that word bold.
 */
const char* const RELS_EN_PT[] = {
  "*$1 em ponto",
  "*$1 e cinco",
  "*$1 e dez",
  "*$1 e um quarto",
  "*$1 e vinte",
  "*$1 e vinte cinco",
  "*$1 e meia",
  "*$1 e trinta e cinco",
  "*$2 menos vinte",
  "*$2 menos um quarto",
  "*$2 menos dez",
  "*$2 menos cinco"
};

I would do the rest, but I have no idea how, sorry...
