Aggregate functions should work on lists

Problem description

Aggregate functions appear to only work on spreadsheet ranges and singularly typed items. The problem is easily shown by putting average(list(1; 2; 3)) in an expression. This cripples the ability to migrate array/lattice parametric wizardry from a spreadsheet to a Property list.
