Firefox throws a SecurityError if user agent tries to set the input element's value programmatically. To prevent this, `autocomplete="off"` is added to the input attributes.

…#467)

Currently isDragActive is true only if all files are going to be accepted.
This has several implications:

1. This doesn't work in Safari since DataTransfer is empty until the drop event
1. The active state should be applyed based on user interaction independently from validation

Closes react-dropzone#440
Fixes react-dropzone#461

BREAKING CHANGE: isDragAccept acts like isDragActive before. isDragActive is true during the drag.

…dropzone#430)

When changing the `accept` prop for the component mid-drag, the component did not reflect the change until you happened to enter/leave another element. This PR updates the `isDragActive` state at the timing of the prop change, using `componentWillReceiveProps`, so the state will be updated right away.

fix: Show rejected style when dragging multiple files when `multiple=…

…=false` (react-dropzone#410)

ATM setting `multiple` to `false` and dragging multiple files into dropzone will display "accepted" styles although only the first file will be accepted and the rest will be skipped.

Changes:

- `onDrop` will be called with first file as `acceptedFiles` argument and the rest of files as `rejected`. 
- To align the implementation with `accept` prop it will also display `rejected` styles in this case.

Closes react-dropzone#409
