Includes support for CommandIR transmitter selection and lockfile.

Usage:
$0 -d delay -c channel -n transmitter_number -s Enter

-c channel or cmd
-n transmitter_number
-s Key to send after executing change channel command (optional)
Sends an IR command or sequence of numbers using via emitter TRANSMITTER_NUM.
DELAY ( in 10th of seconds) is waited between sending IR commands.
Example: Change to channel 123 using emitter 2 with a 0.3s pause between digits:
$0 -n1 -c123 -d3
