I'm adding setIcon function for Windows.

• [x] set icon by specifying file name for debug
• [x] set icon by File
• [ ] set icon by bytes

Let’s postpone “set icon by bytes” to another PR. I’m not sure we want to bring bitmaps and encoder/decoder to the codebase. Loading from file should be enough for now.

Can you please resolve current conflicts and add dummy setIcon implementations for WindowX11.java and WindowMac.java? Just simple

@Override
public Window setIcon(File path) {
  // TODO #95
  return this;
}

So that they continue to compile? Thanks!

And thank you for your contribution, that’s pretty substantial and an imporant feature.
