determine how long after each attack we wait before allowing a new attack to start during the boss fight

[TheAfroOfDoom]

when an attack terminates, it sets the boss_fight entities boss-fight.attack.delay score to a value that represents how long until the boss fight starts another attack.

currently every attack's value here is set to 1s (20 ticks); this is a placeholder value.

you should run the boss fight multiple times and see how the delay between attacks feels.

for example, if x-bullets-upper ends and homing-vines feels like it takes awhile to start, you should decrease boss-fight.attack.delay for x-bullets-upper so that it doesn't wait as long after it finishes before giving control back to the boss fight
