Add 1px margin that servers as gap between posts and list entries to activate :hover pointer cursor

[seanvelasco]

When navigating links, and the cursor happens to fall on a link, the cursor reverts to the default cursor.

Ideally, the cursor should still be a pointer. One way to fix is giving links a tiny breathing room between them. When the cursor travels this gap and falls on a link, the cursor should be a pointer.

This is already implemented for the left sidebar navigation and posts. However, this is not yet implemented for other lists.

Styling-wise, if the entries are not meant to have a border, a gap between entries or an invisible bottom margin per entry should suffice.
