Small stability release for Ashley entity framework this time.

Bug fix: fixed IllegalArgumentException thrown when trying to remove components from an already reset entity. The call has no effect now. Thanks for that SgtCoDFish.

Bug fix: fixed family match failure due to silly silly hashing.

Bug fix: fixed entity.getId() always returning `` for recycled pooled entities.

Bug fix: fixed nested iteration problem caused by adding/removing entities from an entity added/removed listener handler.

Bug fix: fixed missing type error in GWT when using PooledEngine. GWT should be quite smooth now.

The new nightly dependency is com.badlogicgames.gdx:ashley:1.3.2-SNAPSHOT.

Big thanks to everyone who reported issues and especially to those who also contributed with PRs. Keep it up!
