[Seaside] Importing halo's from Monticello

VW specific FYI:

In VW, literals are marked as immutable, so storing into the literal
will cause an error.  You can mark the literal as mutable.

You can load the CompileTimeEval package from the Cincom public
repository to get the VA style compile-time evaluation.
