React Redux Form v0.9.12

• The .npmignore file now ignores .babelrc and other unnecessary files, especially to fix React Native issues.
• Peer dependencies updated to allow for react@15.
• The <Field model="..."> prop now also supports functions that take the state as an argument and return a string model.
  • This is especially useful for the new track(...) function, also introduced in this version (stable, but still being developed)
  • This will be developed further with official usage notes in v0.10.0
• The createFieldClass function now takes defaultProps as its second argument.
  • This is used to fix the React Native issue of wrongly using a wrapper div instead of a wrapper View.
• All tests pass with React v15, and more enhancements are coming to ensure full support (and no warnings/deprecations) of React v15 and <= v0.14 in React-Redux-Form v1.0!
