@define: NestedTypes style type specs for props

[gaperton]

Special case for @define

    props: {
        name     : Task.Collection.has.changeEvents( true ), // = undefined, track changes
        selected : Function // = undefined
        className : 'something' // string, default value
    }

Simplified type specs. Options supported:

• generate React.PropTypes for every type mentioned.
• default values for primitive types only.
• .has.changeEvents( 'event1 event2' ) - if specified, track events for specified property and call forceUpdate.

generate default props and propTypes automatically.
