V0.1.0

I've been planning this for some time but had not the time to do it.

In v0.1.0, as exposed on some issues, will contain:

- [x] Change object name to `QCodeDecoder` (it was `QRCodeDecoder`)
- [x] No more `console.log`
- [x] new `jshint.rc`
- [x] watcher for `gulp build` and `gulp hint`
- [x] add a `prepareImage` method so that one can decode directly from an image
- [x] new example containing `decodeImage` method
- [x] no more `setDecoderCallback` method
- [x] keep searching for new qrcodes by default
- [x] expose a `once` argument for the `decodeFromCamera` method
- [x] remove `prepareCanvas` as this is just used internally 
- [x] add `decodeFromVideo` method
- [x] add automated tests
  - [x] for video
  - [x] for image
- [x] test browser support
