* Examples: Removed deprecated THREE.ClosedSplineCurve3

This commit replaces THREE.ClosedSplineCurve3 with
THREE.CatmullRomCurve3

And remove one `console.log`

Removal of unnecessary continue statements

ensure that "THREE.CLASSNAME:" prefixes all warnings and errors.  Redirect two console.log warnings to THREE.warning for improved robustness.

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

Fixes #5570

Removed Vector* add() to addVectors() and addSelf() to add(). Same with sub, cross, min, max, lerp... Renamed Matrix* and Quaternion multiply() to multiplyMatrices(), multiplyQuaternions() and multiplySelf() to multiply(). See #2860.
Good thing we have a ton of examples to make sure nothing is broken. The unit tests also helped. However, I suspect I've left something unchanged.

- Path.js (esp. Arcs) is still confusing, but as of now
- Ellipses should work
- Path still uses "PATH.ACTIONS"
- the internal curve representation doesn't seem to be used yet
- Path.arc() uses .absarc() which uses .absellipse()
- examples/webgl_geometry_shapes.html should run now
