Switched to using OF_KEY_XXX when possible (everything but CAPS).
Switched to using ofEvents instead of directly calling ofBaseApp::keyPressed(...) / ofBaseApp::keyReleased(...)
Cleaned up a touch.
Using ofEvents() like a boss. No more forward references to ofxSoftKeyboard in ofxSoftKey.
Updated copyright notice.
Added optional frame to draw().
Replaced OF_KEY_DEL by OF_KEY_BACKSPACE in layouts.
