This commit makes operator[] on Vector const and adds a write proxy to it. From now on writes to Vectors need to happen through the .write proxy. So for instance: Vector<int> vec; vec.push_back(10); std::cout << vec[0] << std::endl; vec.write[0] = 20; Failing to use the .write proxy will cause a compilation error. In addition COWable datatypes can now embed a CowData pointer to their data. This means that String, CharString, and VMap no longer use or derive from Vector. _ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug builds. This is a lot faster for Vector in the editor and while running tests. The reason why this difference used to exist is because force-inlined methods used to give a bad debugging experience. After extensive testing with modern compilers this is no longer the case.
