.babelrc should not be published

[maxprilutskiy]

Library exposes complied JavaScript (ES5) from lib and es folders. However, there's a .babelrc file in the root of the package, which sometimes interfere with how bundlers work: if bundler sees such a file in the package it tries to run babel with provided config. But it's obvious that I don't have various presets (react/es2015/stage-1) installed initially - and I don't have to, as far as package exposes already compiled code.

Thus, in order for budlers to work correctly there're two solutions:

1. Move babel-preset-react, babel-preset-es2015, babel-preset-stage-1 from devDependencies to dependencies section, so after npm i has run they got installed and babel would process existing .babelrc correctly (which is noop btw);
2. Remove .babelrc from published package, because library code is already compiled.

I'm gonna issue a PR for this enhancement.
