Fix parsing for empty lines and removing stars on data that spans over multiple lines.

Fix parsing problems for data spanning over multiple lines, it didn't remove the stars.
Also empty lines would cause apiGroup to include star i the name.

These problems only occurs when you have your block comments indented.

Example.
```
/**
 * @api {get} /user/:id Read data of a User
 * @apiVersion 0.3.0
 * @apiName GetUser
 * @apiGroup User
 *
 */

	/**
	 * @api {post} /user Create user
	 * @apiVersion 0.3.0
	 * @apiName GetUser
	 * @apiGroup User
	 *
	 * @apiParam {Object} foo
	 *
	 * @apiDescription first line
	 * second line
	 */
```
