Addresses various bug-reports and recommendations relating to recent number-line and graph-paper updates:
- Enforce reasonable ranges for the sliders governing the grid parameters, taking the grid-size, coarse-grid-size , and playfield dimensions into account.
- Provide a button to request 'graph paper' from the 'generic property sheet' when appropriate.
- Retain position of number line when its pixelsPerUnit changes.
- Disable the 'offset' when coarse-grid in effect.
- Protect sliders against zero-divide that can happen if minVal = maxVal.
- Protect InfiniteForms against incidental calls to #darker and #twiceDarker that can be sent to any object's fillStyle by some of the custom border code.
- Removes about a dozen superfluous methods that had mistakenly lingered in the earlier updates, and removes three inst vars of NumberLineMorph that were remnants from earlier code
