fix interoperability with react-native-router-flux 4

see #42 for more details

we have changed our internals but we haven't broken any our public API. As a nice consequence the performance should be improved.

Optional Back button integration

• now you can use our default implementation of backhandler (that closes menu on back button) or integrate your backhandler more easily if you have special needs.
• this functionality must be explicitly switched on (see API or examples)
• this functionality requires RN 0.44 but this version works also with older versions!

External prop-types (React 16)

Breaking change:

• Switch to new (React 16 ready) prop-types ( @DrPandemic )
  • works only with newer versions of RN (check compatibility table)

Improvements:

• Better warning messages

Unofficial UWP support

According to the community this version should work for RN Windows. Although we don't make any promises to officially support it (won't test any future releases against UWP).

bugfixes

• View.propTypes deprection in RN 0.44 fixed
• closing animation for controlled menus fixed

fix compatibility with older RN version

tested with RN 0.25 (but theoretically should work with RN 0.18)

backdrop animation added

backdrop is now also animated. it has real effect only if you style your backdrop.

small improvements

• even more styling options ( menu trigger can be flex now )
• add imperative methods also to Menu for more convenience

Added closing animations

• default context menu now animates also during closing (not only opening)
• opening/closing durations were aligned with material design guidelines (are bigger than previously)

25% performance improvement
