Quickfix: do not lazy load auth mechanisms for ext storages

Prerender file list pages to include search results

show which login name to use for the new app password

Keep encryption enabled if decrypting for single user

Add explicit delete permission to link shares

Make code integrity check work when OC is not installed yet

Some auth mechanisms like SessionCredentials need to register hooks
early, so they cannot be lazy loaded.

Remove tooltip when disconnecting token

Remove ie8+9 support

Remove a fed share from the local table before trying to notify the remote server

Use OC.Backbone instead of Backbone directly in authtoken JS code

check login name when authenticating via token and basic auth

Fix search result link for file results outside default list

Show error message when posting an invalid comment

When decrypting all files of a single user, the admin usually does not
intend encryption to be suddenly disabled for everyone. This fix
reenables encryption after decrypting for a single user.

Decrypting for all users will still disable encryption globally.

When filtering the file list, if a result is on an unrendered page,
make sure to call _nextPage() to prerender the pages in order to
display all matching results.

When clicking on a folder result in the search result list, the result
box for "results in another folder" must disappear.

When outside the "All files" list, the search result link must properly
redirect to the "All files" list.

Add option to `occ files_external:list` to show all configured mounts

When an internal server error occurs while creating or updating a
comment, display a proper error notification in the UI.

Link shares always allowed deletion, however internally the permissions
were stored as 7 which lacked delete permissions. This created an
inconsistency in the Webdav permissions.

This fix makes sure we include delete permissions in the share
permissions, which now become 15.

In case a client is still passing 7 for legacy reasons, it gets
converted automatically to 15.

Don't reload page in case of auth errors during setup checks
