Add support for namespaced default values

[Alhadis]

Both of these lines are valid JSDoc constructs:

/**
 * @param {Object} [name=Default.value]
 * @param {Object} [name=defaultValue]
 */

A @param tag's default-value accepts anything that a @type parameter does, so whatever's valid as a @type is also valid as a default value:

/**
 * @type {Default.value}
 * @type {defaultValue}
*/

@50Wliu Any thoughts on adding JavaScript highlighting to inline @examples inside JSDoc comments?

It'd be limited to captured regions only, so there's no risk of a begin/end pattern slipping past a terminating */ boundary and ruining the rest of the document's highlighting.

Sure.
