Support image specific style properties (ex. tintColor)

[torbjorn-kvist]

Tested on 1.3.5 and 1.4.0-rc React Native: 0.47

"Warning: Failed prop type: Invalid props.style key tintColor supplied to ActivityIndicator."

Suggested solutions:

• Image specific style property
• Omit "tintColor", "resizeMode" etc when setting styles for View and ActivityIndicator

@Dvidan Sounds good! If you can create a quick PR for this it would be amazing.

Not sure what's the best way yo go about it tho.. Should we have a whitelist/blacklist for props? Or maybe simply have a higher level props for handling the different components, i.e. containerViewStyles, imageStyles (which could just be style), loadingIndicatorStyles?

Would love to hear some thoughts about it

@kfiroo Not sure either I have gotten it to work by doing _.omit(flattenStyle(style), ['resizeMode', 'tintColor']) for example. Problem with that is if there is going to be a more Image specific style properties, then there is a need to update the omit each time there is something new.

Using higher level props could also work.

One other alternativ is to import http://facebook.github.io/react-native/docs/imagestyleproptypes.html https://facebook.github.io/react-native/docs/viewstyleproptypes.html

And use lodash 'difference' and then omit the image specific values.
