    Slightly increase handle and connection point size
    
    as discussed on the mailing list:
    https://mail.gnome.org/archives/dia-list/2014-November/msg00016.html
    
    Also moved the definition for CPs out of lib/connectionpoint.h,
    they were only supposed to be used by app/connectionpoint_ops.c
