Support for cursor up/down escape codes

iTerm does not handle the cursor next line or cursor previous line ANSI escape codes.
http://en.wikipedia.org/wiki/ANSI_escape_code
Example of moving cursor to the previous line (where ^[ is escape, which in bash you can enter with CTRL-V ESC):
Terminal $ echo -e "old\n^[[1Fnew"
new
iTerm $ echo -e "old\n^[[1Fnew"
old
new
There are probably other escape codes that iTerm doesn't yet support, but these were the ones that I had a ready test / use case for.
