Add "Heal" button outside of combat

Currently, we can only use health packs in the "Prepare for Battle" stage. However, after a hard battle, it's sometimes best to use a few health packs to balance the default-10 regen time and your roster's healing time.

Adding a "Heal" button on a character's profile (near "Train Powers" and "Increase Level", for example) would be handy.
