Seperated Zip steps into seperate functions && Added file comparison && Now using /tmp for file operations && Experimental color output && Added extra file and directory logic
Seperated Pacman Database into it's own function so that when the function is called two times it doesn't actually do it. Added a way to compare two files by reading every byte and then checking if it's the same or not. For convenience sake the /tmp directory will be used for all temporary file operations like compressing. Color output is going great. Looks pretty nice. Before doing anything file related all functions check if the necessary directory exists.
