[freeciv-ai] do not allow 100% tax on despotism

[Jordi Negrevernis i Font <jorneg@xxxxxxxxxxx>]

   Sometimes the ai gets stopped in a 100% tax under despotism and 
can't change to republic to research more easily.
   This normally happens when the ai begins to build defensive units 
like crazy.
   This little patch does not leave the ai reach more that 80% tax 
under despotism. The check for despotism is more comparing strings; i 
don't know if there is a better way.
