Touch/Mouse area of wavelength sliders #63

In interviews, we saw a student wanting to click on the gaussian and the thin portion of the slider the chooses the bulb color. Seems to make sense to make the touch/mouse area extend to these portions of the slider.

I have made this change for both wavelength sliders. I left the mouse area smaller than the touch area, but still extended it over the track. Try running color-vision_en.html?showPointerAreas to see if it looks right to you.

The pointerAreasOverTrack option added by this issue turned out to be problematic, and is scheduled to be removed. See https://github.com/phetsims/scenery-phet/issues/261#issue-172560572 for problems, see https://github.com/phetsims/scenery-phet/issues/261#issuecomment-241761531 for solution.
