This adds a second variant for the existing "attribute" function. The current function requires both a target feature and attribute name to be specified, while the NEW variant just uses the current feature. E.g. NEW: attribute( 'name' ) -> returns the value stored in 'name' attribute for the current feature EXISTING: attribute( @atlas_feature, 'name' ) -> returns value stored in 'name' attribute for the current atlas feature It's just a faster shorthand version!
