Sharp AQUOS power button script

# File:  tv_power.py
# Title: Sharp AQUOS power button script
#
# Brief:
#     Connects to the TV over LAN and toggles it on/off.
#
#     TV must first be set up to connect to wi-fi and enable remote access (via on-screen menu),
#     and have LAN turn-on enabled (by sending "RSPW2   " over putty or hyperterm).
#     I use Intelliremote to kick off this script with my media center remote.
