Push Eve to 0.8.2 (dev branch for now).

Created by: NotSpecial

For editing file lists comfortably, in particular to replace single files, clients need to download all files, as Eve currently accepts only the list as a whole for patches, i.e. single items cannot be replaced without sending all others.

Downloading the files in javascript is currently impossible, as Eve does not supply the needed CORS headers to the media endpoint. Eve 0.8.2 fixes this, but is not yet released.

As file list editing of significant importance for the new amiv website (for studydocs), we have decided to switch to the currentl development branch of Eve. We can switch back to pypi as soon as 0.8.2. is released.

Aside from that, Eve made some internal changes to the response class, which required an update to one of our hooks for the case of file passthrough.
