Fix globalservers for Elite Force

Vanilla Q3 UI doesn't list multiple master servers. ioquake3 changed
globalservers 0 to be all masters so they show in Q3 UI, moving single
masters from 0-4 to 1-5.

Vanilla Elite Force on the other hand, uses 0-4 for separate master
servers. So restore that behavior.
