Some more global definition to autogenerate a "Shared by Link" with token! Why we not add these lines for more global use of the public service feature? At the moment there is a pr for sharing a calendar by Link. With this little mod the calendar can work with the core share api and needs no own js share definition!

Fix #4823

Optimize some queries that are always executed when loading base.php

Disable login button until the timezone is set

For some reason IE8 didn't like the sort function, so using the one from
underscore instead.

- fix when URL contains an invalid view id
- viewer mode now hides the sidebar (ex: text editor)
- added unit tests for trashbin
- clean up storage info in template (most is retrieved via ajax call now)

- FileList is now an instantiable class
- FileActions is now in namespace
- added App class for trashbin app
- moved trashbin overrides into classes extending FileList
- replaced many static calls with "this." or "self." to make the classes
  reusable/extendable
- new URL parameter "view" to specify which view is shown, for example
  "files" or "trashbin"
- added OC.Util.History utility class in core for handling history
- moved URL handling/routing to OCA.Files.App
- popstate will correctly update the current view and notify the view of
  the URL change so it can update the current dir
- added JS unitt tests for the trashbin app
- fixed public app to work with the new namespaces

- added new OCA.Files namespace for files classes
- the sidebar can now switch between views/containers
- the trashbin renders in its own container but currently doesn't work
  due to overrides
- added app.js as entry point for JS code (ideally all other files should
  only contain classes and not trigger anything)

Apps can now register navigation items into the sidebar of the files app.
For every sidebar item there is a container.
The container's content is rendered based on the script name given at
registration time.

- Added links to trashbin and shared dir
- Moved "WebDAV" settings block to the app nav's settings section
- Added sidebar support in trashbin app as well

[regression] Fixed trashbin to use correct class

It seems that \OC_Filesystemview has been removed.
Now using the correct class \OC\Files\View()
