energy modifier based on player age

[frolic]

to give death more meaning, we could allow for a slowly increasing energy modifier based on how long you've been alive

for example, we could say that after 14 or 30 days of staying alive, your player burns 2x less energy on actions (and cap it there)

DUST-37 energy modifier based on player age

[frolic]

could potentially be expanded to have skill-based energy modifiers, like more mining = more efficient at mining

not sure if we're concerned about gas of adding extra write calls for every action to track this though
