#3 Configuration for Lua scripts

[Xales]

Another mode for the bot executable which allows Lua scripts to specify configuration options they have (Standard library could use some) and runs a wizard to config them and write them out (config.lua) similar to the "setup" mode.
config.lua may be too ambiguous (the other config file is config)

Possibly move lua to a subdirectory and have conf.d-like subdirectory of the lua directory? Config callback?
