Update #5.1 Hotfix

Fixed a game-crashing bug, and while I was puttering around the code fixed a few miscellaneous bugs. Some miscellaneous optimizing happened as well, simplifying some planetary effects and reducing the number of draw calls to keep your GPU happy!

-Getting critical hits while using Nadia no longer crashes the game -Meteors stop advancing when game is paused -If you clip into a wall, you can always walk out of it -Miscellaneous optimizations
