HolopadSystem needs work

[metalgearsloth]

Top 3 content contender atm. Also the code currently does not support loading.

tl;dr is it doesn't work with persistence and is very slow.

Issues:

• It's using an update timer which is bad and breaks save/load.
• It's always updating UI state globally even if nothing is using holopads.
• It's allocating an entire dictionary separately for every holopad whenever they update.
• GetLinkedHolopads is allocating an entirely new set every single time.
• IsSourceInRangeOfReceiver is being called twice in telephonesystem when the check is the exact same between the two for the second half of it.
• RequiresPower is just duplicating NeedsPower.
• The timespans aren't considering pause (though they're not being used as datafields so I imagine if it gets saved midcall it just leaves a dangling entity around?)
• None of the stateful data is using datafields so holopads won't function if you save and load a postinit map.

There's more but these are just some examples for reference.
