#80335 got the go-ahead from JonBob to commit port to 5.0, patch by dopry, yched, drewish, edrex, and KarenS

of forms. Those using views.module may have to re-save views after this change.
Custom node templates will need to be renamed.

This commit changes the storage mechanism for hopefully the final time. As
was discussed a while back, now data is stored in tables for each content
type unless it cannot be. It may require per-field storage for two reasons:
- The field is present in more than one content type.
- The field allows multiple values.

Per-field help text. Currently only visible in text widget; to be added to
all widgets.
