Allow script arrays to hold any value type, add script engine tests, archive old rpg code

Remove the per-array type category so arrays can mix types like structs.
Add 13 passing and 125 expected-failure duskscript test fixtures with a
table-driven runner. Also includes the in-progress entity/physics and
archive moves from the working tree.
