Fix endless loop on /BIP LIST connections with long on_connect_send

- when the line to send to IRC was over a specific limit, the code was
  not moving to the next item in the on_connect_send list after sending
  the text to the client
- this change also adds a hard limit of 10 on_connect_send to display
  for each connection
