Ratio winner should be fixed to include cases where there is no wining ration presented#69

This is a simple suggestion.
I won a game where I converted 1 unit and lost 0 to conversions.
Another player lost one unit to conversion and converted 0.
1/0 = -
0/1=0
The other player got the best conversion ratio.
This also occurs for buildings destroyed. I lost 0 buildings and still lost with a - ratio to another player with buildings lost.

I can replicate this in the conversions column with the better ratio line thing under red’s 0. I was expecting a star and got a little confused looking at the conversions/desertions column next to it 11
