#606: [raster] ST_Value should return NULL for nodata values

There is two options for returning nodata values.
1) Nodata values are REAL nodata values and there is NO value, period. In
this case ST_Value should return NULL.
2) We want to be able to do computation with nodata values. In this case
ST_Value should return the nodata value.
Up to now I have a strong preference for 2) and plan to change the
behavior of ST_Value. Still thinking about the impacts though...
