Invalid go code: "-" in struct names

[andygrunwald]

If you compile this:

{
    "$schema": "http://json-schema.org/draft-04/schema#",
    "name": "Repository Configuration",
    "type": "object",
    "additionalProperties": false,
    "required": [ "name" ],
    "properties": {
        "name": {
            "type": "string",
            "description": "Repository name."
        },
        "include-filename": {
            "type": "string",
            "description": "Specify filename instead of default include/all${SHA1_HASH}.json"
        }
    }
}

you will get this as a result:

package main

type Root struct {
  Include-filename string `json:"include-filename,omitempty"`
  Name string `json:"name,omitempty"`
}

As you see the var Include-filename includes a - which leads to invalid go code

Thanks for raising the issue!
