Log:
2008-02-02  Murray Cumming  <murrayc murrayc com>

* gio/giomm/contenttype.cc:
* gio/giomm/contenttype.h: Use convert_return_gchar_ptr_to_ustring() 
because it releases the gchar* and checks for NULL.
Removed the ontent_type_guess() that takes a basic_string<guchar> 
because I doubt anybody would use that. Added one that takes a 
gchar* and size, and one that takes a std::string (for when the data is 
a string).
