provide file with content to export

Browse source 
Rather than providing the key to export, provide the file.

When exporting a treeish that contains files that are not annexed,
this will let the content of those files also be exported.

There's still a Key in the interface; it will be used by the external
special remote protocol. A SHA1 key can be used when exporting
non-annexed files.
