Subject: [PATCH] made the lua app preload libraries and indicate how much time
 was spent loading them

the lua shell (or lua app) before this update was loading all the system
libraries for every command, which makes them slower to actually start
running (about 1.5s of delay). in this update, lua starts loading all
the libraries when the shell starts.
