Making eLua script

About eLua Scripts
eLua scripts should be saved to $HOME/STM32/elua/romfs directory. Compiling packs all scripts in romfs into firmware which is flashed to board.

If romfs has autorun.lua script, it is started automatically after power on or reset.

Otherwise script must be started from eLua command line in serial terminal, as in Testing eLua
