Add MVC bindings configurator

[abogarsukov]

Bindings management appears to be quite messy if done manually. Need to add helper scriptable object with custom editor script for this. It should automate the following:

• Update the prefab list;
• Bind specific controller to the prefab;
• Validate the bindings list;
• Auto-reset the list from specific folders;
• Add new controller/view/prefab (codegen).
