Various user experience/error reporting improvements

- Show version as part of the initial message of &bitlbee
- Use g_strerror() to show actual errors when saving xml configs
- Only show "The nick is (probably) not registered" for ENOENT, use
  g_strerror() for the rest of OS errors when loading xml configs
- Show "Protocol not found: <name>" when find_protocol() returns null,
  useful when the user uninstalls a plugin accidentally.
- Suggest the user to check the system clock when getting error 401 from
  the twitter stream (other REST endpoints show a better error message)
