- Thanks @Mugen87!

* convert to ES modules

* rebuild

* move shaders back into glsl files

* reinstate polyfills

* CurvePath: getPoints() should respect last point

- autoClose behaviour now checks first point
- ShapeUtils.triangulateShape to remove dup points
- #9079
- Thank you @@rfm1201 again!

* Update webgl_geometry_text_pnltri example too

* Consistent getPoints and getSpacedPoints on ellipse

They work as getSpacedPoints used to (but with the final point)
The arc between aStartAngle and aEndAngle is always forced in the 0, 2
PI area, as getSpacedPoints did (but not getPoints)

* Refactor Path class

- got rid of .actions
- getPoints() moved to CurvePath
- toShapes() moved to new class ShapePath

* Path: simplify usage of this.currentPoint

* Optimize LineCurve.getPoint(1) as suggested by @rfm1201 in #8952

- this minimizes some floating point errors when t = 1

* Fix up missing changes to CurvePath and EllipseCurve

- as commented by @rfm1201
- using f040453 as reference

* Path: update currentPoint for .splineThru(), add automatic lineTo()

- for ellipse

* CurvePath: address some removeDuplicatesInAPath() concerns

- also cleanup some old reference to .actions

* Path/CurvePath getPoints() shouldn't return sequence of duplicate points

* In path.absellipse, lineTo is drawn only to connect existing path

And remove one `console.log`

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

Fixes #5570

THREE.Shape.Utils.triangulateShape:  Performance of removeHoles improved if there are several hundred holes

Fixed issues in the triangulateShape method (a for..in loop was used where a sequential for loop is required). 
A for..in loop should be avoided when using array like objects, because it also enumerates inherited properties and iteration order is not guaranteed.

partial solution to Issue #3386: rewritten THREE.Shape.Utils.triangulateShape; THREE.FontUtils.snip prevents triangles with duplicate points; Test: http://jsfiddle.net/H794a/
