CVS commit by rchern: 

Autogenerate markers from curves.
Notes: 
- Curves will add markers, but will not remove existing ones, even when changing from one curve to another as source, or if points are altered in an existing curve.
- Manually removed markers that were created by curves will be readded at the next update (if the curve is still used for auto-generation)
- Only changes in y values of data points from 0 to non-zero, or non-zero to 0 are detected.  Changes from negative to positive for example will not be detected (is this correct behaviour?)
