Nyall Dawson 390cb760c9 [feature][expressions] Add feature_id(some feature) function ...

Allows for retrieving the feature ID of a feature object. Accepts
one argument which must be a feature object. Accordingly this
function can be used with the results of any other function
which returns feature objects, such as "get_feature", "overlay_*",
etc.
