use arguments variable to simplify ThreeJS error/warning handlers per @mrdoob's comments here: https://github.com/mrdoob/three.js/pull/5791#issuecomment-67733222

add THREE.error/THREE.warning to allow for easy redirection of THREE.js specific errors and warnings.

I often end up adding custom properties to my `THREE.Object3D` objects but it is hard to use my custom parameters to find objects. Right now there are two specific methods to find objects by a property. `getObjectById` and `getObjectByName`. My suggestion is to add a less specific getObjectByProperty method with as first param the `propertyName` or 'name' and second param `propertyValue` or 'value'. We are able to reuse this new method in `getObjectById` and `getObjectByName`. This ends up in less code with more flexibility.

An additional suggestion would be to add a get method to find by `uuid` like this:

`````
getObjectByUuid: function ( uuid, recursive ) {

    return this.getObjectByProperty( 'uuid', uuid, recursive );

},

`````

I hope you guys also see advantages in this change.

I'm seeing people modifying it :(

This may help on GC and/or be VM friendlier.

WebGLRenderer: Deallocate Object when removed from scene graph (no need for object.dispose()). See #5269.

Remove blend weight accumulators from THREE.Object3D - they have been moved to the animationCache object created by THREE.Animation.

Now is possible to do:

    obj.remove( obj2, obj3 );

From discussion in #4958, see also #4977.

Now is possible to do:

    obj.add( obj2, obj3 );

As well as:

    obj.add( obj2 ).add( obj3 );

Fixes #4958.
