descr: Open Upload rest call for Open Content.

Everybody can upload videos (and set metadata) to one client applications (if it is allowed). The upload call will be available without tickets for these client applications.

This rest call must be implemented on the openapi interface. This rest call doesn't need an ega authentication.

parameters:
- MediaItem? data:  http://opensocial-resources.googlecode.com/svn/spec/1.1/Social-Data.xml#MediaItem

response:
normal rest xml, atom, rss, json

@Robert:
The solution is in the repository.
It is quite a big change set.
- New calls for upload: album/$album_id(/mediaitem(/$mediaitem_id))
- Support POST data upload.
- Output format for OpenAPI is depend on the request header and from the "Request-Parameter-Format-Value" variable.
- Default response type development (admin page).
- JSON and XML development for the OpenAPI standard.
- OpeanAPI upload test.

Reviewed.

For security reason all the OpenAPI REST call was prefixed with "openapi".
Then the REST calls are:
/openapi/album/$album_id [POST]
/openapi/album/$album_id/mediaitem/$mediaitem_id [POST]
