New "Restart" string.

* UserInterface/Views/FrameTreeElement.js:
(WebInspector.FrameTreeElement.prototype.updateStatusForMainFrame):
(WebInspector.FrameTreeElement.prototype._updateDownloadButton):
Update the tooltip when in a non-Web debuggable, and only show
the Download button when in a Web debuggable.

* UserInterface/Views/TreeElementStatusButton.js:
(WebInspector.TreeElementStatusButton.prototype.set hidden):
Oops! The implementation was backwards. Simplify with classList.toggle.
