Add debug flag

[tomkel]

iectrl should have an option to allow the user to see what it's doing, like in ievms. When calling iectrl there is no output. If the program hangs, the user has no way of knowing.

I was able to get some output by debugging to console.log by default.

It's not ideal, but set this variable in your console for debug messages.

export DEBUG='iectrl:*'
