We no longer have the `paper` script around, and as such the docs for it are
stale, and we should remove them.
This additionally adds a tiny note about compilation possibly failing when you
work without a complete patch-set.
Paper will routinely modify your PR for you to rebase it on latest or take care of any minor nitpicks that we can
just solve for you instead of making you go back for a trivial item.
However, if you use an Organization for the PR, this prevents Paper from doing this, and will require us to manually
merge it and close the PR instead of it being marked as the purple merged.
We much prefer to have merged PR's show as merged, so please do not use organizations repo's for PR as GitHub sadly
does not support maintainers pushing to them.
