Subject: [PATCH] replacements: add media_asset_id, old_media_asset_id columns.

Add media_asset_id and old_media_asset_id columns for associating replacements with media assets.
This way we can easily tell which replacements don't have a media asset (with the md5 alone we can't
tell whether the media asset actually exists).
