<h3>Log Message</h3>
<pre>Web Inspector: Refactoring: remove DebuggerTreeElement class
https://bugs.webkit.org/show_bug.cgi?id=169697

Reviewed by Devin Rousso.

Remove unnecessary class DebuggerTreeElement from TreeElement class hierarchy.
The `sourceCodeLocation` property on IssueMessage and Breakpoint (the debugger
objects) can be tested for generically using TreeElement.prototype.representedObject.

* UserInterface/Main.html:
Remove file.

* UserInterface/Views/BreakpointTreeElement.js:
* UserInterface/Views/IssueTreeElement.js:
Change base class to GeneralTreeElement.

* UserInterface/Views/DebuggerSidebarPanel.js:
(WebInspector.DebuggerSidebarPanel.prototype._addBreakpoint):
(WebInspector.DebuggerSidebarPanel.prototype._compareTreeElements):
(WebInspector.DebuggerSidebarPanel.prototype._addIssue):
(WebInspector.DebuggerSidebarPanel.prototype._compareDebuggerTreeElements): Deleted.
Renamed to just &quot;_compareTreeElements&quot;.

* UserInterface/Views/DebuggerTreeElement.js: Removed.</pre>
