patrick 81ddfd450a Use custom foliage flavor 
With this patch, properties specific to variable, function, and
predicate declarations are directly stored within those objects rather
than external maps that need to be queried via traits. This greatly
simplifies many parts of the logic.

This is made possible by implementing a custom foliage flavor, which
makes it possible to swap the built-in declaration types for extended
versions of those types that fulfill certain requirements.
