Problems:
HTML's native <button> tag doesn't support flex styling in all browsers,
causing layout bugs. And buttons or links created by "createDOMElement"
(without an accessibility role) do not have the correct props.
Solution:
The "button" role is rendered to a "div[role=button]" that is focusable
and responds to the same keyboard events as a native button. A native
button can still be rendered using "createDOMElement".
Make "createDOMProps" aware of the component context to ensure style
resets and other props are correctly applied when an accessibility role
is not defined.
Additionally:
This patch also adds a new "label" role to support accessible forms.
It maps to a native label element.

Problem:
The content of style sheets was being set as a child of 'style', which
causes React to escape the content. This meant that the pointer-events
selectors were broken (">" became ">") and pointer-events were
disabled for the entire server-rendered document.
Solution:
Use 'dangerouslySetInnerHTML' to avoid the CSS text being escaped.
Fix#546
Include modifier keys in the 'nativeEvent'. This allows keyboard
shortcuts such as "Shift+Enter" to be implemented for submiting text
input content when the modality is keyboard + mouse rather than touch.
This changes the return value of 'getApplication' so that the
application element and stylesheets are all available as React elements.
Also changes StyleSheet's 'renderToString' to 'getStyleSheets'.
Fix#504
Fixes dozens of Flow errors; adds type annotations; marks more files for
Flow type checking. Fixes a bug in 'AppState'.
15 Flow errors remaining. Several React Native files are still not type
checked (e.g., PanResponder, Touchables)
Ref #465
* Change 'accessible' to align with React Native.
* Add support for 'importantForAccessibility'.
* Stop event propagation for keyboard-activated Touchables (nested
Touchables now respond the same as when touch-activated).
* Fix whitespace layout of nested Text elements.
* Use 'div' for Text to improve TalkBack grouping.
* Rewrite accessibility docs.
Close#382Fix#408
Shim the 'hitSlop' prop using a positioned element to extend the size of
a View's touch target without changing layout. Unlike the native
implementation, the touch target may extend past the parent view bounds.
1. Fix auto-flipping of styles
The StyleRegistry didn't account for LTR/RTL when caching the results of
style resolution. The 'writingDirection' style is no longer flipped; no
clear use case for it.
2. Remove experimental '$noI18n' style prop suffix
This feature is essentially unused, and less likely to be used with the
introduction of 'dir=auto' on 'Text'. Removing also marginally improves
render performance.
