Generate PropTypes Tables from Source Code

[ykadosh]

Currently, we have to manually maintain our props tables, which is error prone.
We can use https://github.com/reactjs/react-docgen to automatically generate those from our source code.

A prerequisite for this task is to expose the prop types from webrix.
Something like:

import {MovableProps} from 'webrix/components';

// Or
import {Movable} from 'webrix/components';
// Access through Movable.Props
