Drive file system local mapping: handling multi-filling

The local database identifies resources using a compound id adapterFactory|repo|id, this system allows to handle both DocumentMode backed items as well as Virtual reources, however, the multi-filling use case (the same file at several placs) is not yet handled correctly.

This will actually be required to handle:

• virtual Folders defined by queries
• documents with attached files
• Picture documents with thumbnails
• LiveEdit working directory integration
