[View] Add support for user timeout + keybinding action

Configuration looks like:

```css
configuration {
  timeout {
      delay:  15;
      action: "kb-cancel";
  }
}
```

Both delay and action need to be set.
Action can be any of the keybindings as shown in `rofi -show keys`.

(-timeout-delay 15 -timeout-action "kb-cancel"  on commandline.).

Fixes: #1066
