Add support for CSP nonces
CSP nonces are a feature available with CSP v2. Basically instead of saying "JS resources from the same domain are ok to be served" we now say "Ressources from everywhere are allowed as long as they add a `nonce` attribute to the script tag with the right nonce.

At the moment the nonce is basically just a `<?php p(base64_encode($_['requesttoken'])) ?>`, we have to decode the requesttoken since `:` is not an allowed value in the nonce. So if somebody does on their own include JS files (instead of using the `addScript` public API, they now must also include that attribute.)

IE does currently not implement CSP v2, thus there is a whitelist included that delivers the new CSP v2 policy to newer browsers. Check http://caniuse.com/#feat=contentsecuritypolicy2 for the current browser support list. An alternative approach would be to just add `'unsafe-inline'` as well as `'unsafe-inline'` is ignored by CSPv2 when a nonce is set. But this would make this security feature unusable at all in IE. Not worth it at the moment IMO.

Implementing this offers the following advantages:

1. **Security:** As we host resources from the same domain by design we don't have to worry about 'self' anymore being in the whitelist
2. **Performance:** We can move oc.js again to inline JS. This makes the loading way quicker as we don't have to load on every load of a new web page a blocking dynamically non-cached JavaScript file.

Initial AppData
* Introduce simpleFS
* Introduce IAppData
* Introduce AppData Factory to get your AppData folder
* Update FileDisplayResponse

* AppData implements a ISimpleRoot but lazy. So only if an apps starts
  to access data will stuff get initialized

Add trict CSP to OCS responses
If a repsonse now explicitly has the Empty CSP set then the middleware
won't touch it.

Add FileDisplayResponse
A lazy implementation of the DisplayResponse that only hits the
filesystem if the etag and mtime do not match.

Deprecate OCSRespone
The OCSResponse should not be used by apps. They should extend the
OCSController and use normal DataResponses instead.

Cache avatars properly
* Set proper caching headers for avatars (15 minutes)
* For our own avatar use some extra logic to invalidate when we update
