module underscore automatically removed

Pageroute currently uses the module name as prefix for the page type name classes. So if a modules name is conte_profile, the class name for the viewprofile page type would have to be content_profilepageviewprofile. I didn't like that so I made a patch that Pageroute removes all underscores.
So the page type class above can now be named ContentProfilePageViewProfile(its case insensitivity).
