Rename query.toJSON to query.json.

[stephenplusplus]

The original PR, #94, made a poor choice in variable naming. We haven't released to npm, so we'd like to change the name before it's permanent.

Instead of:

table.read({
  keys: [...],
  columns: [...],
  toJSON: true
}, function(err, rows) {
  var row = rows[0]
  // row.Name = 'value'
})

This seems better:

table.read({
  keys: [...],
  columns: [...],
  json: true // <--
}, function(err, rows) {
  var row = rows[0]
  // row.Name = 'value'
})
