Have "Display creatures" panel show health of creatures

[tiger_eye]

Having "Display creatures" panel also show the health of creatures has been suggested before, so I'm just *bumping* this idea up again so it will be noticed. Maybe it could also show the tile of the creature .

More suggestions on this window:

• make it always visible, not a toggle window between hotkeys and this (maybe optionally)
• when hovering over a monster in the list with my mouse, highlight it on the game window
