Resource generator should be able to generate JSON

[markbates]

Currently the resource generator only generates HTML resources. It should be able to generate JSON resources as well.

A flag will be needed to do this:

$ buffalo g resource --type=json users name email

When generating a JSON resource, no template files should be generated, and instead of r.HTML("template.html") being used in actions it should be r.JSON(model).

@markbates I can take this one if you want.

i have modified model_templates with this code:

func (a *{{.model_name}}) ToJSON() ([]byte, error) {
	res, err := json.Marshal(a.ToHash())
	return res, err
}

func (a *{{.model_name}}) ToHash() map[string]interface{} {
	res := map[string]interface{}{
		{{range $a := .model.Attributes -}}"{{$a.Names.Original}}":         {{if eq $a.Names.Original "created_at"}}ISOTimeFormat(a.{{$a.Names.Original}}){{else if eq $a.Names.Original "updated_at"}}ISOTimeFormat(a.{{$a.Names.Original}}){{else}}a.{{$a.Names.Original}}{{end}},
		{{end -}}
	}
	return res
}

and this declared somewhere in models directory

func ISOTimeFormat(pTime time.Time) string {
	if pTime.Year() <= 1 {
		return ""
	}
	return pTime.UTC().Format("2006-01-02T15:04:05")+"Z"//for utc
}

and also, ive replaced with my own command with copy of original code to generate reactjs+redux templates :)
