Rewrote the entire code for handling --totals to work with -i

Now for every -t, it checks source dir for existence, and if it's empty before creating the output file
Eg:
  -t Totals /asdf ~/Templates /fads -t Totals_2 /sgsdfg /etc/ssh ~/Templates -i

will NOT create/change "Totals" because all it's folders either don't exist (/asdf, /fads), or are empty (~/Templates)
it WILL create/replace "Totals_2" because "/etc/ssh" exists, and is not empty, and will write in the output file that
   "/sgsdfg" doesn't exist, and "~/Templates" is empty
