Restore "Forks" to Paste
Summary:
I just put them in the property table instead of a list at the foot, they looked weird down there and were too bulky relative to their importance.
This won't scale great if someone forks a paste ten thousand times or whatever, but we can deal with that when we get there.
Also clean up a few things and tweak some styles,
Test Plan: Looked at forked, unforked pastes.
