Sanitising IR codes (for new plugin for KIRA)

[krambriw]

Just to avoid double effort, I'm currently writing on a script that is implementing the conversion from raw pronto -> KeeneIR format

After support from Mark at Keene Electronics, I have ported some java code to a simple python script. The script converts pronto code to KeeneIR format. It would not be hard to update the KeeneIR plugin using the functions to enable the plugin to support pronto codes directly

Attached is also the EG xml-file that can be used. Just open it and run the script

Kind regards, Walter

That's really good stuff, I'll try and get it incorporated this weekend!
