Cleanup project structure

Restructured the project somewhat and cleaned up classes so that things are where they belong. Created "Helpers" folder and put appropriate helper classes in there.

Important things:
- The "GameObject path" methods are now extension methods on UnityEngine.Transform
- Removed AccessTools (Reflection helpers) as there was no use of it. Replaced with ReflectionHelpers class.
- Some improvements to the "Object Reflection" window, should be a bit faster now. Code cleaned up significantly.
