Add a "Skip Folder Configuration" button in the wizard

This allow to start owncloud the first time but not automatically sync
everything, but let the user configure sub folders instead
Always handle 401 requests, except for network jobs

It is not enough to only implement it for the QNAM returned
by the ShibbolethCredentials, because we sometimes need it
when we have no valid credentials set (and are using dummy
credentials in the course).  The main use case is the
Webview opened by Shibboleth for FBA.

But as a side-effect, we can use it to handle auth requests
from the updater and other places.

FolderMan: Proper singleton implementation.

The connect in SocketAPI had to be moved because it also uses
FolderMan::instance(). And since SocketAPI is instanciated in
FolderMans constructor, this was a deadlock.

Now the connect is tried on every new socket connection in SocketAPI
but I assume that multiple attempts to connect are not an issue.
