Remove logging in init()

I'd like to remove this Craft::info() call from init() since it creates a lot of noise in log files.

Probably agree, this formed part of the scaffolding (by the awesome pluginfactory.io) that we used when first building plugins. Does potentially add a fair few lines to the log file. Will look to update.

Could be added as a preference in the plugin settings, to enable log info output?

We could add this as an option to disable info level logging?
