Subject: [PATCH] formData fields support.

This will enable the Parser to parse field parts included in formData. Ej. (parsed data):
parts:
{ name: 'name', data: 'test product' }
{ name: 'code', data: 'product code' }
{ name: 'category', data: 'product category' }
{ filename: 'productImage.jpg',
  type: 'image/jpeg',
  data: <Buffer ef bf bd ef bf bd ef bf bd ef bf bd 00 10 4a 46 49 46 00 01 01 00 00 01 00 01 00 00 ef bf bd ef bf bd 00 43 00 03 02 02 02 02 02 03 02 02 02 03 03 03 ... > }
