Add ability to provide custom height className (Fixes #20)

[le0nik]

It works by adding height property with the className value to the transitionName object.

<ReactCSSTransitionReplace transitionName={{ height: 'cross-fade-height' }}>
  <div key="page01">
    My page 01 content
  </div>
</ReactCSSTransitionReplace>

Nevermind. I'm maintaining my own fork of this module now: https://github.com/le0nik/react-css-transition-replace-plus

@le0nik you've done some great work on this module! Thanks for all that.

I'm sorry that I wasn't able to get round to it sooner. Everything you've done is now incorporated in this main repo and published as v2.0.0 and I've take care to maintain you as the author on your commits.

It would be a pity to see this module diverge into different packages unnecessarily, so if you want to make large scale changes/additions again in the future and aren't set on maintaining your own fork let me know and I'll make you a collaborator on this repo/npm.

I'm glad you're back!

I've added a deprecation notice to README.md and deprecated the package on npm.

Thanks for taking the time to incorporate the changes into this repo.

No problem, and thanks for deprecating the other. Next time I'll be sure to at least leave a reply sooner! Funny how PRs always seem to arise in the most hectic times. 😊
