WebUI: Some changes

I didn't add this, but just don't use _updateSpeedInBrowserTitleBarLinkCheckState()_ (by the way, given that this is the WebUI, isn't "InBrowser" and "in_browser" implied? You can make every var/name shorter by omitting it) on init. Just add somewhere in the code:
```
if (localStorage.getItem('speed_in_browser_title_bar') == "true")
    /* show checkbox */
```
