Issue #128 resolved
Remove distiction between "point" and "solid" entities: unify them.
The distinction between "point" and "solid" entities should be removed: both types of entity should be unified into a single entity type that is capable of both.
- This might also be the natural conclusion should we decide, following
#125, to introduce a component system for entities as well.
- As a welcome side effect, the
func_wallentity class becomes redundant and should be removed as well.
