FormData methods for inspection and modification

The FormData object allows pages to programmatically construct a list of key/value entries that can be submitted via XHR just like an HTML form. Previously, the object was write-only via a single append() method. The spec was fleshed out to add has(), get(), getAll(), delete(), set(), entries(), keys(), values(), forEach() and Symbol.iterator() methods to allow inspection, iteration and modification.
