Added Invincible Visitor settings.

This led to work to enable saving of the config.yml file with comments.
I added the ability to have multiple lines of comments as annotations.
I also enabled comments to align with the exact path of the field.
To do this I used BSBConfig for the Settings class and retired ISettings
When the plugin disables, it now saves the config.yml with comments and
the Invincible Visitor settings.

Note that any settings in the config.yml stored in the jar will still
exist in the file and stay there unless they are manually deleted. They
just will not have any comments on them after saving.
