Replace rayEllipsoidIntersectionInterval with pointInEllipsoid.

The intersection line was being drawn quite differently from
the actual boundary of the intersection.  The latter was being
done correctly, the former was inaccurate.  I took the math from
the working one and applied it to the broken one.
Fix stray "shooting rays" effect spotted by @mramato.
Tighten the clamp.
Restore the check for missing the ellipsoid.
Possible fix for polylines on Linux and Android.
Move debugger logic out of specFilter to fix #659
Merge pull request #697 from AnalyticalGraphicsInc/sensor-intersection

Fix sensor intersection rendering.
Fix nested suite filtering.

A spec should be run if:

* The spec is focused.
* The spec's suite is focused.
* Any of the spec's suite's parentSuites are focused.

Move debugger logic out of specFilter to fix #659
Merge pull request #709 from AnalyticalGraphicsInc/fixNestedSuiteFiltering

Fix nested suite filtering.
Don't run beforeAll/afterAll functions if all specs are filtered out for that suite.

This improves test speed, especially when running "category=none".

Minor license wording tweaks
Ignore polylines with less than 2 points.

Previously the check for polyline length happened in `PolylineBucket.prototype.getPolylinePositionsLength`, but this is too late in some circumstance and causes us to index out of bounds of the position array.  This showed up with #706. We now check for length > 1 in sortPolylinesIntoBuckets, which occurs much earlier in the pipeline

I also removed a bunch of unecessary color parameters from the unit tests.
