Changes to compile for KSP 0.90

Seems to work ok with the Hodor config.
The red kerbin one falls over on the gradient (an exception because a value is already in the sorted list).  I'll investigate this to see if it caused by 0.90 changes to the stock Kerbin.
I'll also test the Eeloo biomes one though this is probably not needed now that Eeloo has biomes in stock.
