Force move attachments to DB storage

In odoo the type of storage is taken from parameter ir_attachment.location. This module move all attachments to a new storage type (db or file) everytime you edit or create the parameter via Settings\Parameters\System Parameters menu.

Right after installing ir_attachment.location is set to db.

To rollback everything, before uninstalling the module set ir_attachment.location to file.

Technical implementation

We use fixed built-in force_storage function to update location for existing attachments.

Note

Be carefull about using Database storage on low memory servers.

Tested on Odoo 8.0 d023c079ed86468436f25da613bf486a4a17d625
