We need to do the redirect to update address bar.

Fixes #952

* Use only the index route (since it went to showFile anyways)
* Fix tests
* Use getUserFolder to force init of users mounts

* Update tests
* Fix getMock in tests

* Move lib/ of Files app to PSR-4

* Move tests to PSR-4

Opening a permalink that points to a trashed file will now display the
file within the "Deleted Files" section in the files web UI.

The following routes will redirect to the files app and display the
matching folder. If the fileid is a file, it will scroll to it.
- http://localhost/owncloud/index.php/f/$fileid
- http://localhost/owncloud/index.php/files/?dir=somedir&fileid=$fileid

add checkbox to toggle show/hide hidden files

persist show hidden setting

fix settings menu layout

test ApiController::showHiddenFiles

don't show hidden files by default

Store config in Backbone model and inject it into FileList

Filter files only temporarily when rending the file list

Fix file rename validation

This is required by the pdf viewer, since the files app on master uses the AppFramework it had applied the more strict defaults which made it not work on master.

1. Allows it to use the more secure CSP rules of the AppFramework.
2. Adds some unit tests.
