EmailProvider now supports query and getType for cached file urls

b/17573792
This is needed so that we can send cached files as attachments.
This case comes up if you edit a draft with an attachment,
view the attachment, and then share that with Email.
Also, update the manifest so that EmailProvider grants
uri permission for cachedFiles.
