Object type support

[antho1404]

Implementation of the objects as an optional property.
It is now possible to have inputs complex like

name: "myservice"
sid: "test"
description: "Description of my service"
tasks:
  taskX:
    inputs:
      foo:
        type: Object
        object:
          x: { type: String }
          yy: { type: Any }
          z: 
            type: String
            repeated: true
        repeated: true
    outputs:
      success:
        data:
          message:
            type: String
