v3.0 Beta 3

• Several cases where filesystem case sensitivity was breaking things have been fixed (notably, if a modfile has capital letters and the game rootfs has posix=1, mods no longer fail to work)
• Fix layeredfs for AVS <= 2.13
• Fix broken texbin rect repacking when the texture name was the same as a rect name
• Special build variants (such as "always logs to file" and "always verbose logs") are now generated, in case you don't trust the commandline args propagating
• The source for the d3d9/opengl32/dxgi injectors is now provided and built in meson
• The zip is now built with build.sh
