Allow for file attachments on talks

[gwolf]

We have got several mails at DebConf content team from people sending us their talk slides. We are basically just copy+pasting the URLs into the abstract. It would be great if Wafer allowed to attach files to talks - Even more so: Would make a lot of sense to allow for this even in approved talks (because authors very seldom have their talk material ready weeks before they present it!)

One can already attach URLs to talks (http://wafer.readthedocs.io/en/latest/talks.html#talk-urls) although it's only possible via the API and the admin interface currently. Questions:

• Is adding a link rather than uploading a file sufficient? E.g. Upload file to the Internet Archive and then link to that, or similar?

• Is requiring an admin to add a link sufficient? Or do we need something more?

Could work, but I think the link should be internal. I consider talk slides to be an important part of the conference's information and history.

* Is requiring an admin to add a link sufficient? Or do we need something more?

If five or six authors upload their slides, I (as an admin) will be happy to add them. If it is sixty of them, I will be very pissed.

We have support for uploading content already for pages, but that does require admin access

We need to provide some wrapper around uploading with suitable permissions checks and automatically generate an url pointing to the internal location. We may need some additional namespacing to avoid name collisions (everyone uses slides.pdf) an maybe some admin options for setting size limits?

Django's media handling should give us that out of the box. It'll rename files to avoid conflicts. But yes, namespacing them is probably going to be even prettier.
