Waiting as a Strategy

We can make the game a little more strategic by allowing the player to deliberately wait and receive some healing as a benefit. The player heals their wounds and hit points are restored. Waiting while adjacent to a monster is a poor choice, as the adventurer is likely to be attacked. If the player wants to give it a try that is their prerogative—dying is often the best way to learn to play a game.

The mechanic of deliberately waiting and healing when inactive is handled entirely within the systems/player_input.rs system. Open the file so we can tweak it a little.
