Bug 18403: Send logged_in_user to template from C4::Auth

Technical note:
To ease future changes we are passing a logged_in_user variable to templates.
It contains the Koha::Patron object representing the logged in patron.
This will be very useful for this patch and even after (for instance we will be
able to replace easily loggedinusername and loggedinusernumber).
