[ogawa.yasufumi at lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi at lab.ntt.co.jp>

Hi,

This update is to fix bugs of topo command.

* Topo command is failed if 'imgcat.sh' which is required only for
  MacOS does not exist. Linux user uses `img2sixel' instead of it.
  It is fixed by changing not to find 'imgcat.sh' if 'img2sixel'
  exits.

* Topo is not update for python 3 and cause an error of encoding.
  To avoid this error, add encoding appropriately.

  controller: fix bug of topo to refer external cmd
  controller: fix encoding in topo command
