Attachment: Truncate DOM attributes in DevTools settings

Long attribute values in the markup view are truncated if the corresponding pref devtools.markup.collapseAttributes is set to true (available as an option in DevTools settings: "Truncate DOM attributes").

It would help developers to show an indicator when truncation is applied so they don't get confused when the attribute value they expect shows up incomplete.

Perhaps it could be made interactive and replace the truncated attribute value with the full value. But just the indicator itself is a first step in reducing confusion (See bug 1632824#).
