v0.5.0

• Optional Promise-based API: if you call any method that takes a
  callback without providing a callback, it will return a Promise:

  table.find(recordId).then(record => {
      // Process record.
  }).catch(err => {
      // Handle error.
  })
  

• Added an all() method for automatically fetching all records
  across all pages when selecting from a table:

  table.select({view: 'Main View').all().then(records => {
      // records array will contain every record in Main View.
  }).catch(err => {
      // Handle error.
  })
