Uses inspector.html instead of devtools.html

Chrome 45 uses /devtools/inspector.html instead of /devtools/devtools.html.

e.g. localhost:9222/json

{
   "description": "",
   "devtoolsFrontendUrl": "/devtools/inspector.html?ws=localhost:9222/devtools/page/57DD6140-1AE2-482A-87F2-6656522AB965",
   "faviconUrl": "https://www.google.com/favicon.ico",
   "id": "57DD6140-1AE2-482A-87F2-6656522AB965",
   "title": "New Tab",
   "type": "page",
   "url": "http://localhost:9222/json",
   "webSocketDebuggerUrl": "ws://localhost:9222/devtools/page/57DD6140-1AE2-482A-87F2-6656522AB965"
}
