Particular caution was exercised with the files in
`OnionSproutsBot/plugins`, which mostly contain excerpts taken
from other files so as to make the source code appear cleaner.

There is a non-negligible chance that I may have missed something,
despite taking at least one hour cross-examining the original sources
of different files and their contents. If this is the case, I will
try my best to amend that in a later commit.

A simple `git blame` cannot properly attribute code in these
situations, which goes on to highlight the necessity of this change,
as people are borrowing excerpts of this codebase and incorporating
it into their own projects.

Being able to figure out who generated each line of code is, in my
honest opinion, of paramount importance.
