Hiemal Shield recharge on rest

[Nekoatl]

If Hiemal Shield is damaged, and enough souls are available for it to successfully recharge, "Rest a while" currently will wait 0 turns if there is not some other target for resting. This means the player must manually click, click, click until the shield recharges, or accept a heightened risk that the shield will be destroyed in combat. It would be nice if "Rest a while" could take the damaged shield status into account when deciding whether or not turns should pass while resting.
