Deduplicate any list

Frequently asked questions
- Is the original order kept?
- Yes. The first occurrence of each line stays in place and later repeats are removed.
- Does it ignore letter case?
- By default yes, so 'Apple' and 'apple' are treated as duplicates. Turn on case sensitivity to keep both.
