allow to pass more props to text widget

[vasilich6107]

Currently we have an ability to pass through textAlign: widget.decoratorProps.textAlign, property.

This PR adds an ability to pass all props supported by Text widget

[salim-lachdhaf]

the added properties are not an InputDecorator props.

imho, you should add a new props named TextProps which contains all text props.

and make two _getBaseTextStyle one for InputDecorator and another for Text (because you will have two TextStyle).

and you can add here the modification (DefaultTextStyle) made on #719 after changing copyWith with merge (same behavior as now).
