Title: easy lua require()

automatically add the folder containing the main lua profile script, to the lua load path. this way, the lua script can easily require() other lua scripts in that folder. example:

require "tag_utilities"
require "lib/tag_utilities"

if you need to require scripts outside this folder, you can still set environment variable LUA_PATH before running the binaries.
