* Don’t create SideMenu button automatically on Android

* Remove left button and add it dynamically

* Fix resetTo animation on Android

Up until now resetTo would destroy the current stack and create a new
one. This was an easy implementation but resulted in jurky
(none existent) animations.
This commit changes resetTo behavior. Instead of recreating the stack,
the we reset to is pushed to the stack, and the other elements are
removed when show animation ends.

Implement collapsing TopTabs on Android

specify `navBarHideOnScroll: true` in your `TopTabsScreen`

* Move event emmiter logic out of Application

* Implement searchView

Usage:
```js
rightButtons: [
      {
        id: 'searchView',
        label: 'Search',
        hint: 'Search...'
      }
    ]
```

* Translucent TitleBar

* Collapse TopBar

* Less noticeable translucent effect

* Implement ScrollViewDetector

Complete collapse on touch up instead of fling

closes #21

closes #312

This is needed since some of the data we need to send in the events
can not be serialised and added to a Bundle.

* Created Snakbar class to encapsulate Snackbar logic.
* Clicking the action now emits event to current screen
* Action color works

This commit closes #224 and fixes #252. Calling `setButtons` with
`leftButton` object still works for now but is deprecated and will be
removed in future version.

This commit adds support for displaying an activity with no animation
by setting `animationType: none` when calling `startApp`. In the future
we can support more animation types if there's a demand for it.
