Options and other containers do not work with boxed types

[gorgonblot]

Creating this issue in swagger-core based on related issue previously raised on spray-swagger (gettyimages/spray-swagger#31).

Consider the Scala example:
@apimodel(description = "Options of boxed types produces an Object ref instead of correct type")
case class BoxedTypesIssue31(stringSeq: Seq[String],
stringOpt: Option[String],
@(ApiModelProperty @field)(value = "Integers in a Sequence Box") intSeq: Seq[Int],
@(ApiModelProperty @field)(value = "Integer in an Option Box") intOpt: Option[Int],
justInt: Int)

Using swagger-core to generate the Swagger Spec results in:

{
"description": "Options of boxed types produces an Object ref instead of correct type",
"id": "BoxedTypesIssue31",
"properties": {
"intOpt": {
"$ref": "Object",
"description": "Integer in an Option Box"
},
"intSeq": {
"description": "Integers in a Sequence Box",
"items": {
"$ref": "Object"
},
"type": "array"
},
"justInt": {
"format": "int32",
"type": "integer"
},
"stringOpt": {
"type": "string"
},
"stringSeq": {
"items": {
"type": "string"
},
"type": "array"
}
}
}

The attributes justInt, stringOpt, and stringSeq are represented as desired.

The attributes intOpt and IntSeq are not. The boxed value is indicated as "$ref": "Object" instead of "type":"integer".

The desired Swagger Spec is:

{
"description": "Options of boxed types produces an Object ref instead of correct type, but can be overcome with dataType",
"id": "BoxedTypesIssue31WithDataType",
"properties": {
"intOpt": {
"description": "Integer in an Option Box",
"format": "int32",
"type": "integer"
},
"intSeq": {
"description": "Integers in a Sequence Box",
"items": {
"format": "int32",
"type": "integer"
},
"type": "array"
},
"justInt": {
"format": "int32",
"type": "integer"
},
"stringOpt": {
"type": "string"
},
"stringSeq": {
"items": {
"type": "string"
},
"type": "array"
}
}
}

I have some code that I will submit as a pull request that resolves this issue (to my satisfaction).
