code optimization &new helper functions added / modified

- UnityCore namespace changed to UnityEngine
- Object class is no longer a template. FindObjectOfType function set to template
- Added LogComponents function. It helps us retrieve components from the target gameObject.
- Added GetObjectName function to Object structure (same method is available in utils header)
- Added ConvertToSystemString function.
Converts const char to system.string (app::String)
