Added missing set_content SQL statement for updating revisions stored in LOBs. This statement was already missing in the release of OpenACS 5.10.0. LOBs are for PostgreSQL somewhat depreacted and these are just there for legacy applications.
new function: ::content::revision::export_to_filesystem
This change moves functionality from file-storage to acs-content-repository. all application packages should be free of internals, such as the storage type. Storage_type should be handeled in the content-repository package.
We are not yet done, there is still more to do in this respect in the file-storage package.
