Send key presses to mythfrontend telnet control

Here is a simple python script that simplifies controlling mythfrontend over a network. It simply captures key presses and sends them to mythfrontend using the telnet interface 'key ...' command.

# Send control keys to mythfrontend. Remember to enable network control
# in the mythfrontend settings.
