Function to divert login links

Any link generated by wp_login_url() will go to home page. But failed
logins and logouts will not still.
I format functions like this
Link in invite email now works again; invited users can only be invited to future race

WP is now encrypting keys
Deleting avatars now works
Whitepage preview is now possible

We need to be able to tell users this is a preview, though
Working on widget builder page
Maybe this shows a preview box, but probably not
