And remove one `console.log`

Removal of unreachable break statement

Fixes #5570

centroid was originally used by CanvasRenderer, now that it computes it as needed we don't need the bloat anymore.

- See #4105

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.

(Phewww!) I'm sure there are still things I missed...

Updated Closure compiler. Added more verbose compile warnings. Fixed all compile warnings. Started to fix runtime warnings in examples.

For verbose compile warnings to be practical I had to add externs and disable some warnings manually (there were tons of complains about "global this" and "cannot instantiate non-constructor"). Other solution would be to annotate explicitly constructors all over the code base.

Curves refactored - addition of curve path, tangent finding, along with other bend changes and enhancements i may not remember
