Removed Old scripts.

- build.sh frog script that is no longer relevant for me.

- ssh_func looks like I was going to write an ssh wrapper. it was empty though.
shifted tmux session control to tmux conf from bashrc

- bash now uses new-session -A to attach to a session created in tmux.conf or
  start a new one if it does not exist.

- yakuake session now has an additional window showing iotop
