Changing translation in pt-br

[pierryangelo]

There are some issues in the brazilian portuguese translation:

less_than                  : "meno que" 

the word "meno" doesn't exist in the language, the correct translation is "menos"

  minute_read                : "minutos de leitura" 

once we can one or more minutes of reading, the plural of the word "minuto" is optional, so we can use "(s)" after the word "minuto" to reflect this

 related_label              : "Você Talvez Goste Também" 

this change is for better reading, the previous translation is not good

I changed the capitalization of the subsequent words for lowercase to have default capitalization in all translations.
You can see the results of this translation in my personal blog, pierryangelo.github.io

Thanks.

Thanks @pierryangelo. Care to add pt-BR translations to these strings (lines 256-266) as well? They've been missing for a while and since you clearly know the language it would be of help.

Here's the English versions below for reference:

comments_title             : "Comments"
comment_form_info          : "Your email address will not be published. Required fields are marked"
comment_form_comment_label : "Comment"
comment_form_md_info       : "Markdown is supported."
comment_form_name_label    : "Name"
comment_form_email_label   : "Email address"
comment_form_website_label : "Website (optional)"
comment_btn_submit         : "Submit Comment"
comment_btn_submitted      : "Submitted"
comment_success_msg        : "Thanks for your comment! It will show on the site once it has been approved."
comment_error_msg          : "Sorry, there was an error with your submission. Please make sure all required fields have been completed and try again."
loading_label              : "Loading..."

Not at all, I'll do that!
