We had some inconsistencies before: - Sometimes "The", sometimes "the" - Sometimes trailing ".", sometimes no trailing "." I picked the most common one (lowecase "the", trailing ".") and applied it to all copyright headers. By using the exact same string everywhere we can ensure nothing gets missed during a global search (and replace), and that these inconsistencies are not spread any further (as copyright headers are commonly copied to new files).
