E8103 error

SavedVariable bound twice with saved.bind

area: stdlib (x8xxx)
fails the build: yes

The same SavedVariable is bound with saved.bind twice in the addon. Each binding would load, fill with defaults and strip the same data on its own, so the two tables would fight over it.

Bind it once, in one module, and export the returned table to the modules that need it.
