#2197: Reorder tabs. Move Upload into file browser.
Improve the private site login form.  Form now loads inside a vsite context and no longer uses purl_goto, so performance gets a nice bump for private sites.  The form now also properly redirects a user to whatever page they are coming from so if they click on a link somewhere to privatesiste/publications/foo, it will redirect them to publications/foo on login rather than just to the vsite homepage as it previously did.  #2378
