Support for Brazilian Portuguese

[tuxslack]

Tested on Void Linux

• Image file format support
• Translation for pt_BR

Some words still need to be translated into Brazilian Portuguese (Add, Delete, Preferences, Apply, Cancel ...).

Add = Adicionar
Delete = Excluir
Preferences = Preferências
Apply = Aplicar
Cancel = Cancelar

Thanks

To translate the words: Apply and Preferences is this correct?
