privatemsg_title_callback and _privatemsg_block_menu functions should be a theme

Regards,

part of the requirements for a project was to have a block including specific content and messages, i think private messages is a great module so far and the fact that includes a block with links is even better, but the only way to overwrite this block content was hacking the module code which everybody already knows is not a good drupal practice.

what i did was create a patch that transform this functions into theme functions, that way we can overwrite them using the template.php file.

i think this option is really important for users that want to modify that content.
