New influence orb (de)spawning method

All orbs are spawned at the start. Instead of destroying them when
touched and respawning them every so and so seconds, they are disabled
when touched, and enabled every couple seconds.

Notes to self: influenceSpawnArea (parent GameEngineServer) has
BoxCollider(trigger) and InfluenceOrbArea.js
