- Implemented keyboard navigation (Up / Down / PgUp / PgDn / ESC). 

- Shadow windows (behind popups) were reacting to mouse clicks and
  were going over the popup. Make them close the popup instead.
- Title was not displayed when the help file was opened by the command
  line.
- Corrected incorrect links behavior (in relation with the scrollbar).
