Fix bug where an avatar that had an object they owned attached through llAttachToAvatar() or osForceAttachToAvatar() would wrongly have next permissions come into play when they detached that object and rezzed it in scene. 

This is because the attachments module code was setting the 'object slam' bit by using PermissionMask.All
Solution here is to route the attachment item creation call through the existing inventory code in BasicInventoryAccessModule rather than copy/pasted code in AttachmentsModule itself.
