- Adds the update_idle_power_usage() and update_active_power_usage() procs for the respective vars.
- Switches all places modifying those vars directly to call the procs instead.
- This will let us react to the change appropriately, paving the way towards static area power.
- Adds update_power_channel proc for the sake of completeness, but no machines actually modify it so far.
- Creates new advanced shield generators, designed to replace old hull and bubble shield generators.
- Upgrades the floor mounted and handheld shield diffusers.
- Makes underfloor shield diffusers actually constructable.
- Handheld diffusers orderable via uplink.
- Removes supply packs and research datums for the old generators, but leaves their code in place for maps that still use them.
- Integrates with the meteor and electrical storm events.
- Integrates with mob AI (they know how to attack it)
* Combat Mechs Can Punch More Things
Removes the var to check for the 5 things it can attack, instead it can punch anything (but not everything will take damage).
Gives punching objects a check so you don't accidently smash something without meaning to.
Gives closets and canisters a proc to take_damage so they'll actually get smashed by the mechs.
* Take_Damage Boogaloo
* More take_damage Stuff
Adds click delay on attacking barriers.
Proper noises when attacking material doors and barricades.
More stuff can be broken by mech punch and simple mobs.
