SkyScraper raweeg export

Hi,

while writing my thesis about brain-computer-interfaces, I found your software and I liked the gui, but I need the raweeg output from the neurosky-bci. So I touched your Software to export the raweeg values in the csv file. It looked to me, that you double commited some sources, so I removed them in my fork. We use jdk8 in our university, so I removed some anonymous classes and rewrote them as lambda expressions. In my fork, I removed the donate button (I don't want to adorn myself with borrowed plumes).

So thanks for your great work! Maybe you'd like to merge.
