Implement Segmented Workflows

A major source of bugs has been how we've approached inlining
workflows. We no longer inline them as of this commit, and instead
use a stack structure. This commits the result of workflows to the
database before other workflows try to read them, so we don't have
to maintain a code path for when something is or isn't committed
to db.

This patchset allows for workflows to pass limited information
to preset selections
