Batch mode displays prompt

[Dean Troyer]

Batch mode is interactive mode with input from a file or stdin w/o a tty (redirected). The prompt string is printed disrupting output. Prompt should be suppressed when stdin is not a tty.

openstack <<EOF
container create qaz wsx
EOF

It seems to be a cmd2 limitation of Cmd.pseudo_raw_input

    Hide prompt in batch/pipe mode

    Currently cliff prints prompt in batch/pipe mode:

    I-AM-A-PROMPT$ echo file | cliffdemo
    (cliffdemo) +---------------+--------------+
    | Field | Value |
    +---------------+--------------+
    | Name | . |
    | Size | 4096 |
    | UID | 1124 |
    | GID | 1000 |
    | Modified Time | 1424473806.9 |
    +---------------+--------------+
    (cliffdemo) I-AM-A-PROMPT$

    This change removes the prompt when batch/pipe mode is detected:

    I-AM-A-PROMPT$ echo file | cliffdemo
    +---------------+--------------+
    | Field | Value |
    +---------------+--------------+
    | Name | . |
    | Size | 4096 |
    | UID | 1124 |
    | GID | 1000 |
    | Modified Time | 1424473806.9 |
    +---------------+--------------+
    I-AM-A-PROMPT$
