Tracker InfoWindow: layoutify, use tabs

- Use layout kit to make a few things simpler
- Separate the view showing the header (icon/name) and the one showing
the extra details, making two simpler files instead of a complex one
- Fix some layouting issues
- The permissions are now in a second tab, allowing to add a third one
with other things (more on that later)
