- Fix typo for *popOver* value of *modalPresentationStyle*. Should be *popover* (lowercase)
- *topBar.buttonColor* is not works, but *leftButtonColor* and *rightButtonColor* instead works perfect

Fix typos in styling.md

the generic buttonColor doesn't work for android. Backbutton color is not documented, see #3454

This property is used to set background color only for components,
unlike backgroundColor which sets color for every type of layout.

Motivation
When a view appears, its options are resolved according to its
currently displayed children. Basically this means that child options
are hoisted to the parent as children can declare options which effect
their parent.
This means that if a component has declared layout.backgroundColor or
if that property was declared in defaultOptions, each view will have a
background color, which might contribute to a significant overdraw.

This property can be used to control how the SideMenu is opened using swipe gesture

bezel - only swipes from the side of the screen open the side menu
entireScreen - Swipe from any area of the screen will open the SideMenu

Until now controlling drawers touch gestures was impossible, drawers received gesture opening touch from the entire screen and that causes collisions with other gestures (which are implemented on the javascript side).

This commit adding modes for how sideMenu drawers gestures will receive opening touch.
```
{
  sideMenu: {
    openGestureMode: 'entireScreen' | 'bezel'
  }
}
```

- `entireScreen`: drawer gesture will trigger drawer opening from the entire screen
- `bezel`: drawer gesture will trigger drawer opening only from the center screen bezel frame

The default didn't change.

Add title alignment to options

Missing 'color' property in the styling docs for the topBar background color.

Kind of a workaround

* Apply BottomTab text and icon color individually

wix-playground/AHBottomNavigation does not support setting color for the entire tab (icon and text),
instead it supports setting color individually to text and icon. Another change is that it no longer supports
default color for icons. If icon color is undefined - it won't tint the icon.
