Nyall Dawson db1a1929a4 [FEATURE][expressions] Simplified variant of "attribute" function 
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!
