IRSS: Migrate Bibliografic-Files to IRSS

This Feature-Request is part of the larger strategy to move all user-uploaded files to the ILIAS Resource Storage Service (see Project: ILIAS Resource Storage Service (IRSS)). Feature requests like this are spin-offs from IRSS: General Overview of Components to Migrate (ongoing) and are basically already approved, we just like to keep track of these.

There are two different approaches:
- Some components used ilObjFile in the past to store files. With ILIAS 7, Files from ilObjFile have been migrated and components using them communicate through a wrapper. These component now must be decoupled from ilObjFile and use the IRSS directly. 
- Some components stored their files on their own in the iliasdata or data Directory. These component should migrate their files to the IRSS using a Setup - Add migrate Command. 

1 Initial Problem

The Bibliografic object currently stores the user-uploaded files itself in the iliasdata directory (.../bibl). These files are to be migrated to the storage service as part of the Project. This is done with the help of a Migrate Commands.

2 Conceptual Summary

With the help of the Migrate Commands, all previously uploaded bibl files are migrated to the IRSS. In the process, the newly created ResourceIdentifications are stored in the table "il_bibl_data" in a new column "rid".
The object is adapted internally so that newly uploaded files are saved in the IRSS.
