fixed forward declaration in ice for skills. Works on Ub20 but not on Ub18. Dont now why, both use 3.7.....

- Move Ice types into data namespace, add native C++ wrappers
- Fix swallowing context menus on error
- Fix breaking on lost connection
- Add "actions" as an interface in the MNS
- Expand on example in ExampleMemory

This avoids skipping the transform begin flag if the client does not request the interaction feedback fast enough.

Also adds actions to the ExampleMemory for demonstration purposes.
