Some work on Linux version
The Linux version will now:
    build.sh:
         Make directories when necessary and terminate if folder src does not exist or no .c* files are in src.
         Put the program in folder bin and copy it to the main directory folder.  This should probably be a link instead.
         Add -ggdb to variable LIBS in preparation for new argument --no-debug.
    install.sh:
         Use invisible folder for installation location.  Switched to /home/$USER/.bin instead of /home/$USER/bin
         If /home/$USER/.bin/buildify exists, it will check the link location and confirm it is linking to the correct location.  If it is not, it will override it.
