Fixes #20. Updated Blender's Settings Dir and added a README so you don't forget it each time you update Blender.

Also updated gitignore to not exclude important folders such as that read me one.

+Updating Bundled Products:
+a) To update the JDK edit ~/jdks/download-jdks.sh and make sure to clean any caches (on CI-Systems like Travis) or delete the file links in ~/jdks/ 
+b) When you update Blender (you already have the folder for that), make sure to also update jme3-blender/src/com/jme3/gde/blender/BlenderTool.java. It contains a getSettings method which WILL break each update. See #20
