Fungaloid rework

[RoyalFox2140]

As per conversations on the discord, my take on improving playing against fungals:

• Zerglike creep and creep tumors. Specifically Starcraft 2 zerg, enemies will create stationary mobs that spread creep but don't fight.
• Colonies: AKA a stationary turret that shoots the player and spreads fungal tiles but only attacks tresspassers
• Fungals get penalties when on neutral ground, tougher and more territorial fungals can be used.
• Slow spread, which is well mitigated by destroying colonies, especially with long-ranged guns.
• All creep disappears after colony/tumor death, and it only spreads so much and so far. Kill a central tower and it all goes away.
• The units can't survive for multiple days off fungal ground. They all clean up after a week of tower death.
• Redo all debuffs associated with them. Spore dusting is especially bad so any good clothing coverage should prevent it.

This slow spreading and easily manageable high risk fungal monsters means they present as a unique and tough obstacle to better guard loot POI's in fun ways, and would only spread out of control if you made a mistake of living near them. They would likely cover more ground by default to compensate for less spread and less nuisance.
