expose useScrapper hook

[kalimantos]

As requested in feature request #77
I changed the input params accepted by the hook in a object config to make the call easier without optional parameters
for example if i want to call useScrapper with just url and onSuccess
before:

useScrapper(
  'myURL', 
  undefined, 
  undefined, 
  undefined, 
  undefined, 
  () => console.log('success!!')
);

after:

useScrapper({
  url: 'myURL',
  onSuccess: () => console.log('success!!')
})
