support property validate and correct

[Javey]

Support validate and correct property like bellow:

class A extends Intact {
    static propTypes = {
        show: Boolean,
        name: {
            type: Number,
            fix: (value) => {
                return Number(value);
            }
        }
}

The fix method is complex. Because it has changed the original property, when the component has received a invalid value again, it may lead to infinite loop. On the other hand, we maybe not only change one property but also set some other states.

Let the $receive event trigger on init is good a choice.

Support validate enumerated type like bellow:

static propTypes = {
    type: ['default', 'primary', 'danger']
}
