I've made changes so that the code compiles and also updated the UI code to no longer use the RenderingManager.
I've verified that the UI shows up and you can generate the graphs, and everything seems to be working.
Comparing the results from TWP to alexmoon's online launch window planner the graphs and results appear very similar, but not exactly the same. I've heard there are some changes between degrees/radians in the KSP APIs in 1.1, but I don't know what's changed or how the TWP internal calculations work, so I figured it would be best if I leave updating that part to you.
