Creating version 1.0

[jstypka]

The underlying neural network framework Keras has recently released a backwards-incompatible version 2.0 with some shiny new stuff. My plan with Magpie would be:

1. Merge those changes and create a GitHub release v1.0 that would point to this commit.
2. Migrate to using Keras v2.0 and create a new release when that's done.
3. Maybe start publishing the releases through PyPI, so we don't need to install it through GitHub.

Tell me what you think @kaplun !

Sounds neat! What about the trained model? Are they still compatible? Right we don't ship with trained models 👍
