- NoPublicBotAttribute will now be properly ignored when built with GlobalNadeko configuration

- Added ILogCommandsService which will have dummy implementation on public bot, this means Logging Commands will be present on public bot to pull up help etc
- When .ve is enabled, NoPublicBot commands will show a nicer error message with link to selfhosting guide (thx ene)
- Fixed xp gain and .xp command not working on new users
- General cleanup
