[.804][SUGGESTION][UI] Overlay Cooldown Time

For the spells that have a cooldown time, instead of just showing them with a lovely read cross denoting you can't cast it, overlay how many turns left until you can.

For example the summon familiar spell has a cooldown time of 200 (turns).  SO after you cast the spell, it shows up with the red cross over it, with a number on the cross saying 189 (meaning 189 turns until you can cast again).
