Fixed save-lineup.php

... because it redirected (at least here...) to error.html although a
lineup file was created.
Reason: "?lineup..." as redirector in line 10 has no information about
a document change, so the client is redirected from "save-lineup.php"
to "save-lineup?lineup...".

Fixed.
- Removed "Player Add" button as it is buggy atm.
- Removed alert which popped up if the entered label is enpty. That was
very annoying. :D
