Server structure defined + functional shift

! This commit will not compile or build or anything fancy like that
+ Server structure defined as having two concurrent actors, the global scene and
  the player manager, which chatter every frame
+ Entity manager and scene manager expanded
- Removed a bunch of shared state by not using classes
