<h3>Log Message</h3>
<pre>Web Inspector: Improve console.trace, make it more like console.assert and inline the message
https://bugs.webkit.org/show_bug.cgi?id=152352

Reviewed by Timothy Hatcher.

* Localizations/en.lproj/localizedStrings.js:
New &quot;Trace&quot; related strings.

* UserInterface/Views/ConsoleMessageView.js:
(WebInspector.ConsoleMessageView.prototype.expand):
Since we auto-expand Trace messages for their Call Stack, don't also
auto-expand a single inner object, which may be big and push the
actual stack trace off the screen.

(WebInspector.ConsoleMessageView.prototype._appendMessageTextAndArguments):
Behave like Assert messages and absorb a message string, and include
extra arguments gracefully.

(WebInspector.ConsoleMessageView.prototype._appendFormattedArguments):
For expandable messages with simple extra arguments (console.trace with
primitives and backtrace, or console.assert with primitives and backtrace)
we were hiding the inline lossless previews and not showing them as a
bulleted list below. We can just keep the lossless previews inline in the
title, since they were only put there because they are small and lossless.

(WebInspector.ConsoleMessageView.prototype.toClipboardString):
No need to hard code &quot;console.trace()&quot; in the clipboard.

* UserInterface/Views/ConsoleMessageView.css:
(.console-message.expandable.expanded :matches(.console-message-preview, .console-message-preview-divider):not(.inline-lossless)):
(.console-message.expandable.expanded :matches(.console-message-preview, .console-message-preview-divider)): Deleted.
Don't hide the inline lossless preview in the console message title when it is inline-lossless.

* UserInterface/Views/ObjectTreeView.js:
(WebInspector.ObjectTreeView.prototype.expand):
Do not allow expanding a loss-less preview.</pre>
