[Freeciv-Dev] (PR#11443) tinfo support patch from ALT Linux

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=11443 >

Here's a patch that reverses the order of checks (to keep the current
order of precedence).  I think this is ok.

We can add a check for tinfo to 2.0 but it should have the lowest
precedence (rather than the highest which this gives it).
