- Attempt to pool PushConstants
— ToDo: Fix cleanup crash / heap corruption

[Ionut]
- Refactor command buffer pooling
- Remove all static commands in an attempt to fix rendering issues. Profile and rework later.

[IonutCava]
- Rework ThreadPool/Task system for clearer parent<->child relationship between tasks
— Disable Prio pool since it doesn’t work properly with the newest boost libraries
— Modify the C++11 threadpool to remove the boost dependency
- Reduce memory usage by allocating command buffers on use instead of on creation

[Ionut]
- Add more DLLs required by CEGUI
- Move CommandBuffer allocation from GFXDevice to GFX namespace

[Ionut]
- Generate GFX::CommandBuffers only from GFX::CommandBufferPools.
— We shouldn’t be allocating any new GFX::CommandBuffers at runtime now.
— ToDo: Add a similar system for Pipelines
- Add 2 command buffer pools to GFXDevice: a primary one used for rendering and a large, secondary one used for command generation
