launch_app not working in 0.5.1

[NotReallyADeveloper]

Following the RFE to allow IPs/IDs to be manually specified #9 , the launch_app parameter no longer works (but same worked in 0.5.0):

when sending msg.payload set to launch_app=com.netflix.Netflix

debug output
Error: Command failed: atvremote --airplay-credentials abcdefghijklmnopqrstuvwxyz launch_app=com.netflix.Netflix

[...]

From the debug message, it would appear that the command isn't passing the actual device.

Sending a simple command, like "play" and "pause" continues to work fine.
