* I2PTunnel standard and IRC clients:

- Allow host:port targets; set defaults in i2ptunnel.config (ticket #1066)
   - Don't fail start if hostname is unresolvable; retry at connect time (ticket #946)
   - Output IRC message on connect fail
   - Update target list on-the-fly when configuration changes
