Entry formating

I'm just properly adjusting and standardizing some entries referring to Portuguese Internet slangs; as they are so they fit in the header "abbreviation" (as most of Internet/texting entries are set here). As to the removal of empty lines, they are sometimes necessary to conform with the rest in this dictionary. I think it would be very confuse if each entry is written in a different way.

The "abbreviation" header has been deprecated for some time now. Entries shouldn't use it, instead the header for the appropriate part of speech should be used.

You also used lang=en in a Portuguese entry, which added categories as if it were English. I try to always click "preview" and look at the entry before I save it, because there are always little details that get overlooked.
