[ENH] Add pt-BR spell & grammar check as full package

[Olivier Hallot]

As for English, Hungarian and Russian, add Brazilian Portuguese package for grammar and spell checks in Ubuntu/Debian.

For en, hu, and ru, there ase the packages:

libreoffice-lightproof-en
libreoffice-lightproof-hu
libreoffice-lightproof-ru-ru

I am asking to add
libreoffice-lightproof-pt-BR

This will avoid many user question on "where is the grammar and spell checker of pt-BR in my linux?".

Source code is in

dictionary/pt-BR/

Information on the spell check and grammar chek of LibreOffice for pt-BR are in (but in portuguese)
