Update package.json to v0.2.9 in preparation for urgent bug fixes.
... I've regressed base component contruction contract for some variants of onm data model semantic bindings in v0.2.8.
This is to be fixed in 0.2.9 and supported by additional deep tests of component creation. Recent enhancements to onm.Store.createComponent are to blame for this regression. That, and inadequate base test coverage.
