Small back end touch ups.

A small back end update to fix a security issue and replace some scripts. Functionally nothing has changed but a few scripts have been looked over and edited to improve stability. Also patched a security problem in Unity that was found and fixed by Unity. This game is a flop but I haven't forgotten it. It has too many controls and became something different to it's original plan. Originally it was supposed to be a top down capital ship combat game, but it became an arcade game, and the mechanics did not mesh well with a faster pace style game play. Lessons have been learned. I will probably come back to try and fix it, or make a squeal that fixes all the issues and delivers more what the game was supposed to be. Thank you for playing Flank Speed, this is not the end.
