Title: Bug XXX, go-out current mark in tabs bar on changing tabs' enable/disable on settings

- bugfix, go-out current mark in tabs bar on changing tabs' enable/disable on settings

- TODO: check item.title is current
I think it use enum like `UIBarButtonSystemItem`

e.g.
```
enum ToolbarPanelItem : Int {

case Tabs
case Bookmarks
case History
case Reader
case Settings

func toString() -> String {
switch self {
case Tabs:
return "Tabs"
case Bookmarks:
return "Bookmarks"
case History:
return "History"
case Reader:
return "Reader"
case Settings:
return "Settings"
}
}
}
```
