Added an emptiness representation in the explorer GUI.

Browse Source 
It's an item displayed on the center of the GUI if there isn't any data to display.

 * NEW: added an item displayed if the explorer GUI is empty.
 * NEW: implementation of this empty item in the list GUI.
 * NEW: small adjustments on the statistics (removed the last empty line from the lore)
 * BUG: the old method was still used to remove the item attributes (the one from the `gui` package).
