normalize and canonize names

[ppKrauss]

Rules to normalize:

• same name same ASCII representation, by unaccent(name) function.
• similar name same Metaphone-pt

Rules to canonize (choice of the official):

1. WHEN same CPF and similar name (or same first names)
   1.1. check official name with a CPF-resolver
   1.2. (if not possible) use the most recent

2. WHEN no CPF and same name (and same birthDate)
   2.1. use the most recent when more than 6 years diff
   2.2. (when else) use the "most accented" version or "most standard pt-BR" (eg. preffer use of i insted y)

... Use some log to notice mesages in conflict resolutions ...

Example:

               name               | birthdate  |           source
