Title: Removes "cool stuff" from Afinn-111 file. It was causing an error in problem 3

This pull request does two things:

1. Removes cool stuff from the sentiments file. If you maintained the words in the original sentiments dictionary for the solution of the problem 3, the system was showing an error:

The error was caused by that word.

(After checking the file, there were other multi-word phrases, this pull request also removes them)

2. Removes an extra space at the end of the file (There is another pull request for this)
