Mainly small install script improvements - Consistent usage of `$LUANHOME`, removed reliance on current directory. - Made Luan build and install fine (on Linux) without requiring launching it via sudo. Only asks to elevate privileges if installation failed. - Minor spelling mistake fix.

cd $localStartup;

	sudo rm ${systemStarup}/${file};
	sudo rm $file;
