now with better options

• added a new menu in the pause screen for the CVARS under the Nuts&Bolts section
• changed rexglue to https://github.com/SolarRecomps/rexglue-ostentation/tree/dev
• fixed an issue where healing caused half the screen to go black
• added a slew of graphics options like removing shadows, particle effects, CAO/SSAO, motion blur, and syncing shaders (these are in the pause menu as well)
