terminal too small throws a silent exception

[bubaflub]

Opening up a new terminal window in iTerm2 defaults (for me) to 80x25. When I run art.py in that window the program immediately exits without any feedback. Looking at at art.log

ERROR:root:Exception: Traceback (most recent call last):
ERROR:root:Exception: File "art.py", line 50, in
main()
ERROR:root:Exception: File "art.py", line 46, in main
matrix.show()
ERROR:root:Exception: File "/Users/bkuo/work/rop/opc/matrix.py", line 212, in show
self.ansi.show(pixels)
ERROR:root:Exception: File "/Users/bkuo/work/rop/opc/ansiclient.py", line 149, in show
stdscr.addstr(" | \n")
ERROR:root:Exception: error: addstr() returned ERR

The terminal window needs to be a bit bigger so it can display. Let's get a better error message to the user.

Thanks, Bob!

Fixed in commit 38004ca.
