Improve the SoC lua menu code to bring it in line with forth
menu functionality

Submitted by: Zakary Nafziger
Sponsored by: FreeBSD Foundation

Use loader.setenv and loader.unsetenv instead of loader.perform

Convert from include("/boot/foo.lua") to foo = require("foo");
to bring in line with latest lua module conventions.

Enforce a uniform style for the new .lua files:
	o hard tab indenation for 8 spaces
	o don't have if foo then bar; else bas; end on one line

MFC After: 1 month
