Remove "List" parameter type and replace all occurences of it with appropriate
multi-valued parameter ("Str" in most cases) with csv enabled.
Add new parameter type "Any", capable of holding values of any type. This is
needed by the "batch" command, as "Str" is not suitable type for the "methods"
parameter.

list and added few more files/directories to it.
