Attached output to the NetBeans Console

Hello,

I've found your Plugin in the NetBeans Plugin Page and I like It. But there was one annoying thing left: I can't see if the Command runns well or not, a output would be nice. So I've added this Function and it works well. Just one file was changed.

Greetings
