Support for doxygen style block comments

when writing block comments it would be nice to have a way to auto indent them and add a '*'

/* This is a comment
 *
 * Some body text
 */

Writing this is tedious at the moment because QtCreator doesn't auto indent when pressing enter on /*.

Can see this would probably have to be an option since people have different conventions but since this is used for doxygen which our project uses and is quite common, it seems reasonable to have as an option.
