Breaking: #60559 - Dropped Backend Login Options 

See forge#60559

Description 

Handling of $GLOBALS['TBE_STYLES']['loginBoxImage_rotationFolder'] and $GLOBALS['TBE_STYLES']['loginBoxImage_author'] was dropped.

Impact 

Setting those options has no effect anymore.

Affected installations 

These options had no effect with standard core internal login screen based on t3skin for a long time already. Instances are only affected if a 3rd party extension is loaded that changes the backend login screen and operates with these settings.

Migration 

Remove these options and their usage from the affected 3rd party extension or unload the extension.
