Footprint wizard: Fix IO exception error in python scripts which happens sometimes, due to the fact these scripts printed messages to a console, but when Pcbnew is not run from a console, there is no IO channel to read these messages. 

The fix is not perfect (still no IO channel to read these messages) ,  but it works better.
Also, fix erroneous comments in code, and cleanup code.
