Entitas-csharp: Generate EntityIndex

[sschmid]

Generate Indexer class for fast lookups for fields in components tagged with [IndexKey]

public class NameComponent {
  [IndexKey]
  public string value;
}

var entity = pool.GetEntityWithNameValue("Player1");

Update:
EntityIndex is already available on develop and can be used.
The code generators are not updated yet. This will probably happen after the typed Entity and Pool is implemented. See #139
