Fixed the description for mode_class

I finally figured out how to do modules with JNI

null actions are now handled gracefully instead of segfaulting the JVM

Added the widget builder API, also fixed the main API which was broken due to using the JNIEnv across threads

Ignored .settings

Added class_path option

Cleaned up includes

The wofi class is now a global reference

Removed unneeded brackets

Consistency is good

First commit
