Upgrade to RN 29.2

Many, many thanks to @wookiem !!!! Don't know what I would have done w/o your help!!!!

Notes

• Once you merge the Snowflake, due to RN 25 issues, updates you'll need to modify any additional react files in your project:
  Instead of:

import React, { Component, PropTypes, View } from 'react-native';

you need to now use:

import React, { Component, PropTypes } from 'react';
import { View } from 'react-native';

• In an effort to keep up w/ the releases of RN, this release is sub-par for Snowflake. There are a number of issues that have to be addressed. I will get to them in the coming days. My immediate concern is trying to get Snowflake in sync w/ RN releases.
• This release contains buck configuration stuff but it's not completed.
• One of the missing features is the SessionToken support.

Please review the following.

• Upgrade Android Support to 23.2.1 to support react-native-vector-icons. see http://stackoverflow.com/questions/38352754/could-not-find-com-android-supportsupport-v423-2-1
• For Android, if using GenyMotion, be sure to follow these instructions: http://stackoverflow.com/questions/35959350/react-native-android-genymotion-adb-server-didnt-ack

There are 3 tests were blocked by other projects:

• Two tests were blocked due to APSL/react-native-button#46

This is temporarily fixed w/ https://github.com/bartonhammond/snowflake-react-native-button

The following two tests were failing:

FAIL  src/components/__tests__/FormButton-test.js (0s)
 Runtime Error
  - TypeError: Cannot read property 'style' of undefined
        at Object.<anonymous> (node_modules/apsl-react-native-button/Button.js:22:25)

and the other:

 FAIL  src/components/__tests__/Header-test.js (0s)
 Runtime Error
  - TypeError: Cannot read property 'style' of undefined
        at Object.<anonymous> (node_modules/apsl-react-native-button/Button.js:22:25)

The other failure is waiting on gcanti/tcomb-form-native#134 so the file has been renamed

 FAIL  src/components/__tests__/LoginForm-test.js (0s)
 Runtime Error
  - Error: Cannot find module './datepicker' from 'index.js'
