Add Lua compiler Redbean Lua Server Pages may now be stored in the zip as byte code. This can improve performance, since redbean currently doesn't cache byte code but it might be more useful for anyone wanting to create a closed source redbean. The .lua extension should be used for byte code files. Lua will tell them apart based on a magic number at the start of the file. This change also improves some Lua error reporting conditions. See #97

DESCRIPTION
Lua is a language designed for embedded use in native applications. It
has an impossibly elegant C API and the Lua language itself feels more
like Python compared to alternatives like Tcl except it's a great deal
faster and doesn't have strong opinions about character encoding.

Lua now uses a bestline REPL with bash-style code completion.
Implement raw system call for redbean lua code You can now call functions like fork() from Lua and it'll work across all supported platforms, including Windows. This gives you a level of control of the system that Lua traditionally hasn't been able to have due to its focus on old portable stdio rather modern POSIX APIs. Demo code has been added to redbean-demo.com to show how it works. This change also modifies Lua so that integer literals with a leading zero will be interpreted as octal. That should help avoid shooting in the foot with POSIX APIs that frequently use octal mode bits. This change fixes a bug in opendir(".") on New Technology. Lastly, redbean will now serve crash reports to private network IPs. This is consistent with other frameworks. However that isn't served to public IPs unless the -E flag is passed to redbean at startup.

Integer literals such as `033` will now be interpreted as octal.

The `\e` string literal escape sequence has been added, which is
equivalent to `\27` (the Lua version of `\033`) or the ASCII ESC
character. It may be used for teletypewriter control like having
bold text, which can be encoded elegantly as `\e[1mHELLO\e[0m`.
