Support for System.Object[] return type

[mikeclayton]

It'd be nice if AutoBot could handle return System.Object[] return values from PowerShell scripts. This should allow him to deal with pipline output.

E.g.

function MultiValueReturn() { "value1"; 100; new-object System.Object; }

returns a System.Object[] containing @("value1", 100, new-object System.Object)
