[IonutCava]
- Remove node and cmd buffers from GFXDevice and add them as a new BufferData struct to RenderPass class.
— Each render pass holds its own buffers
- Improvements / fixes to the CSM code
- Added a global toggle to enable/disable custom memory allocators

[Ionut]
- Custom memory allocation system part 1:
— Add http://www.codeproject.com/Articles/1089905/A-Custom-STL-std-allocator-Replacement-Improves-Pe
— Add custom allocators to strings and vectors
— Add custom allocators to a few test classes
— No support for aligned memory yet, so vec4<F32> and mat4<F32> vectors use the old allocation system
- Replace more std::async call with our custom task system

[IonutCava]
- Update copyright notice
- Move BoundingBox and BoundingSphere to a new BoundsComponent
— Add a temp hack in SceneGraphNode to update these

[IonutCava]
- Fix and optimize particle rendering system
- Temporarily disable Z_PRE_PASS system for testing
- Improve thread pool destruction system a bit
- Fix texture loading when used as fb attachment
- Forward+ renderer now takes the entire light buffer (no need to split up by light type)
- Start work on occlusion culling fixes:
— ToDo: Take into account batching system
— Fix gl_DrawIDARB usage

- More work on the ForwardPlus renderer
- Singleton cleanup
- First steps for reducing scope of GFXDevice class

[IonutCava]
- Improved multi-threaded culling
- Increased nodeBuffer size to avoid different render stages to override each-other’s data and wait for locks
- Added a indirect command buffer per render stage

[IonutCava]
- Profiler guided optimizations:
— Replace most hashMaps with vectors where the common access pattern is linear (e.g. SceneGraphNode’s child list)
— Specify ShaderBuffer access patters at creation time to properly inform the rendering API
— Fix and optimise the LockManager & BufferLockManager classes
— Add a AtomicWrapper class that allows assignment and copy-constructions for atomic variables
-— This allows us to use vector of atomic bools for BB creation for SkinnedSubMesh objects
