Modify Shape2D so that it manages its own vertex buffer rather than using the draw list (#1249)
* - modify Shape2D so that it manages its own vertex buffer * - fix the last commit failing on Shape2Ds that were modified after AddShape was called * - make buffers an array of F2DVertexBuffers instead of an array of pointers * - fix AddShape with the same VBO but different transformation crashing the game * - formatting fixes
