New version of JSPWiki

I uploaded a new version of JSPWiki. It has attachment feature enabled, one can download and upload attachments to the pages. An example of page having attachment added - look here.
To keep attachments a Blob data type is used. Source code to entity is here, it is simple key (page name) -> Blob content schema. So it shares 1MB limitation of blob size.
It is possible to overcome this limitation by using Google App Engine Blobstore service , no problem to replace WikiPageBlob entity with Blobstore Api. It is also possible to combine this two options together, attachments less then 1MB keep in entity, for greater attachment use Blobstore service.
