Update install_*_packages.sh lists (except for OS X)

Add NO_STDIO_REDIRECT define to C::B build

Fix problem where files were opening in text mode, even when using _O_BINARY

Start switching scripts over to use lgob instead of lgi

Standardize on Lua 5.1

Lua 5.1 doesn't have LUA_OK, switch to 0

Don't define O_BINARY if it's missing (probably still have to remove it from w_wad for *nix*)

Switch scripting namespace from "xf" to "d2k".

Pull out the name of the script folder and the name of the init script; should probably make these command-line switches at some point
