PtitPass por GrandLu

PtitlLu wanted to generate passwords, so this add-on allows us to generate random passwords of given length between 6 and 100 characters.
Uses all characters that can be included in modern passwords:
- Uppercase letters: A-Z
- Lowercase letters: a-z
- Numbers: 0-9
- Symbols: ~`! @#$%^&*()_-+={[}]|\:;"'<,>.?/
- Space (only between other characters)
