not be shown because the view was created before the resource load
finished. The right view is now created, even if the resource isn't
finished. The SourceView just makes sure to not load the source until
the resource is finished. Only if the category changes, does the view
need to be recreated.

* page/inspector/Resource.js:
(WebInspector.Resource.prototype.set category): Call recreateViewForResourceIfNeeded.
* page/inspector/ResourcesPanel.js:
(WebInspector.ResourcesPanel.prototype.recreateViewForResourceIfNeeded):
Added. Tries to make a new view, if the view is the same prototype of the
previous view, return early. If they differ, close and detach the old view
and associate the resource with the new view. Calling updateErrorsAndWarnings
is needed, because the errors and warnings that might have been added to the
previous view will be lost, so make the tree element match.
(WebInspector.Resource.prototype._createResourceView): Always create a view
that matches the resource category. Ignore the loading and failed status.
* page/inspector/SourceView.js:
(WebInspector.SourceView.prototype.setupSourceFrameIfNeeded): Don't setup the
frame if the resource hasn't finished or if the load failed.
