GreyFold

Copperbox revision 380.

I've added another module to GreyFold - SynthethicFolds. These are the folds that can be defined in terms of foldl or foldr - countfold, statefold, double accumulator fold - all they actually do is partition the summary value in some way, so they can be defined on Foldable types.

Also, I've added mergesort to the Data.Sequence compatibility functions.
