Add multi-file paste formatting.
Also auto-scroll long content.
Make a default setting for if pastes are private.
Hide the 'private' checkbox for always-private.
Remove the nonfunctional /all/ link.
Add privacy defaults to the API too.
Remove some unused stuff.
Add space between multi-file headers.
Format line numbers with ordered lists.

This allows line wrapping without the numbers getting desynced for wrapped
lines. It looks way better for stuff with long lines to have it natively
wrapped instead of scrolling.
Add toggle-able line wrapping.
