Added the resources/ folder. It's to store our Icons and other (graphical) stuff centralized.

+## What does this folder do?
+This folder is no common resources/ folder as in it’d be processed by the build process.  
+This is just for the sole purpose of storing the downsampled Icons and other resources so you don’t have to do this all over again.  
+
+### HOW TO properly generate Icons
+The process of generating Icons shouldn't be necessary but who knows  what the future brings.  
+You basically have on large file (256x256px) with 32bit color-depth and have to downsample that for .ico's  
+
+Windows Icons contain multiple images with different resolutions to pick them based on the platform.  
+I included a GIMP project file, however feel free what Software you'd use.  
+
+Essentially you have to create different layers and then the GIMP Exporter (Export -> Windows Icon) does all the work for you.  
+See here for the correct configuration:

+
+### HOW TO Replace Icons:
+When a new Netbeans Version is out you might need to redo this process since we override netbeans launcher exe with our version (and this launcher can change with a new nb version).  
+See `harness-override/README.md` for more information on that subject.  
+
+Open up `app.exe`, `app64.exe` and `pre7_app.exe` (*not* `pre7_app_w.exe`*!!*) with the `Resource Hacker` Software (or comparable).  
+Open up the `Icon Group (100: 1033)` and Right-Click on it to select `Replace Icon`.  
+Select `jmonkeyplatform.ico` and you’re done. (Well, save the file ;))  
+
+Note: Your Windows has an Icon Cache so you can’t see that it actually worked.
+Simply launch `ie4uinit.exe -ClearIconCache` and it should work.
+
+[There’s](http://www.sevenforums.com/tutorials/49819-icon-cache-rebuild.html) a larger tutorial but it shouldn’t be necessary.
+
+When you’ve changed the Icon, make sure to change the hashes in `harness-override/override.properties`
+You have the „hashBefore“ and „hashAfter“. The first one is the plain .exe before changing (This is so we can see if there’s a new netbeans version without us having changed the icons/exe) and the other one is after changing. Simple, huh?
+
+Then issue `shasum -a 256 netbeans/harness/launchers/*.exe` so you have all the hashBefore’s / After’s
+See `harness-override/README.md` for more information on that subject.
