Add 'method' option

[tony-ist]

In ajaxSubmit there is line:

method = options.type || this.attr2('method');

And what if options has only method and no type specified? According to jquery reference, method is alias for type. Maybe add both?

jQuery 1.9.0 prefers setting method (values: "GET", "POST", "PUT")
Prior to 1.9.0, must use legacy setting type (same values)
