Config.yml has new options: hologram-view-distance, health-bars
Placeholders that contained stage in the name changed: {stage_timer} -> {phase_timer}

- Added new health placeholders and custom health bar placeholders

- Added custom health bars to be used with placeholders. Instead of the neanderthal tricks used in chop_tree.yml

- Generator stage(s) is now referred to as Generator phase(s)

- Holograms now update when the health of the generator changes, instead of using a timer where a fast update is required.

- Reworked placeholder/function system to be 99% nicer to look at and performant. Also allowing for future possibilities such as per action placeholders.

- Added default hologram view distance in config.yml
