Code generation fails for path parameters of type array that have no items specified

[Sjeiti]

While this is legal in Swagger 2.0

swagger: 2.0
(...)
paths:  /search:
    get:
      (...)
      parameters:
        - name: term
          in: query
          description: search string
          required: false
          type: string

ng-swagger-gen will fail with Error: TypeError: Cannot read property 'type' of undefined because it expects the items to be defined (like so):

swagger: 2.0
(...)
paths:  /search:
    get:
      (...)
      parameters:
        - name: term
          in: query
          description: search string
          required: false
          type: string
          items:
            type: string

This can be fixed by defaulting type itemType (ln 908) to string
