networked-hand-controls issues with aframe-v1.5.0

[bruce90j]

The networked-hand-controls component doesn't work properly with aframe-v1.5.0:

1. Hand color is not updated (example: networked-hand-controls="hand:left;color:gold;").
   To make it work replace:
   

   networked-aframe/src/components/networked-hand-controls.js

   Lines 219 to 220 in 0f84523

   	const handMaterial = newMesh.children[1].material;
   	handMaterial.color = new THREE.Color(this.data.color);

   
   with:

   const handColor = this.data.color;
   newMesh.traverse(function (object) {
       if (!object.isMesh) { return; }
       object.material.color = new THREE.Color(handColor);
   });
   

2. Hand controller does not work if controllerComponent is not specified (example: networked-hand-controls="hand:right;handModelStyle:controller;").
   Remove 'gearvr-controls', 'daydream-controls' from the controllerComponents list:

   networked-aframe/src/components/networked-hand-controls.js

   Lines 235 to 249 in 0f84523

   	controllerComponents: [
   	'magicleap-controls',
   	'vive-controls',
   	'oculus-touch-controls',
   	'windows-motion-controls',
   	'hp-mixed-reality-controls',
   	// these were missing from the original hand-controls component:
   	'valve-index-controls',
   	// some older models that it doesn't hurt to include:
   	'oculus-go-controls',
   	'gearvr-controls',
   	'daydream-controls',
   	'vive-focus-controls',
   	],
