Changes

**Glide64mk2 is just Glide64 with additional tweaks and enhancements for use with Mupen64Plus. The cxd4 plugin is a port of BatCat's RSP plugin for Project64. You will need to enable "DisplayListToGraphicsPlugin" in the cxd4-ssse3 settings for this to work. This appears to be the best combination for use with most games, though toasters may have performance issues. If the mk2 variant is too slow, try regular Glide64.
