make star at beginning of each line optional and align parameters

I didn't like the way `VVDocumenter` prefixed each comment line with a star, so I made that optional.

I also made `VVBaseCommenter` align the names and 'contents' of `@params`. So what previously looked like this:

````
/**
 * <#Description#>
 *
 * @param first <#first description#>
 * @param aSecondOne <#aSecondOne description#>
 * @param andThird <#andThird description#>
 */
- (void)someMethod:(id)first withSome:(id)aSecondOne arguments:(id)andThird
````

now looks like this:

````
/**
 * <#Description#>
 *
 * @param first      <#first description#>
 * @param aSecondOne <#aSecondOne description#>
 * @param andThird   <#andThird description#>
 */
- (void)someMethod:(id)first withSome:(id)aSecondOne arguments:(id)andThird
````

This can currently not be turned off, but I can make it an option if you'd rather have it be disableable.
