Typo

This reverts commit dd1b19c3.

#14606: `OBJLoader2` allows to register a generic error handler. If this callback is available it will be used instead of a throw. `LoaderWorkerDirector` uses this callback to report a problem, but continue with the next loading task.
`OBJLoader2.loadMtl` now allows to pass onProgress and onError as well.

- three.js issue 13197:
  - Added forceWorkerDataCopy to THREE.LoaderSupport.WorkerSupport and THREE.LoaderSupport.WorkerDirector
  - THREE.OBJLoader2 handles cached resources properly. This increases overall performance as no unnecessary reloads are requested.
- THREE.OBJLoader2: Reduced Parser complexity:
  - Simplified slash counting used for face type detection
  - One buildFace fucntion is used for all four face types, lines and points including indices (=vertex reduction) creation if wanted.
  - String processing (o, g, mtllib and usemtl) just concatenates chars
  - Overall speed improvements due simpler code paths
- Removed THREE.LoaderSupport.ConsoleLogger: Added setLogging function as replacement where. Console logging is behind boolean flags.
- Removed THREE.LoaderSupport.LoaderBase: Many functions are coupled with OBJLoader2. It was simply not generic enough and added unneeded complexity.
- Reduced THREE.LoaderSupport.PrepData to minimum set of generic functions. Simple properties are added by demand and are no longer enforced.
- Renamed THREE.LoaderSupport.Builder to THREE.LoaderSupport.MeshBuilder
- Updated documentation

OrgRepoIssue 28: Parser Validation. Parser now is one single class: Simplified code, fixed bugs missing 'g' statements and introduced obj_obj2 verification with gulpfile to re-create verify.obj.
OrgRepoIssue 31: Worker code still works when mangling is used during minification. Needed to remove Consts.
OrgRepoIssue 32: THREE.LoaderSupport.ConsoleLogger: Allow to pass additional arguments to error, warn, info and debug
OrgRepoIssue 33: Added support for Points and fixed Lines along
- Removed Tr instruction from verify.mtl
- WorkerSupport.buildSingelton allows to use constructors from functions list (fixed singleton typo along)
- Builder defines the default materials and renamed 'vertexColorMaterial' to 'defaultVertexColorMaterial' for consistency.
- Fixed Builder.updateMaterials clone instructions
- Extracted load and checkResourceDescriptorFiles to LoaderBase.
- loadMtl now allows to pass material options to MTLLoader
- Updated documentation

WWParallels demo use the same logger everywhere now.
Updated documentation.

Fixed issue 15: better user control over console logging
Fixed issue 16: use event objects in callbacks and numerical progress in onProgress
Updated version to V2.0.0
