--User changes

-Edits will not save back to the file in memory on render completion when preview renderer is running.

--Bug fixes
 -dc_perlin was crashing on Nvidia when using SP.
 -Duplicate images were randomly getting added to the file in memory.
 -Crash when opening an Xml with less than 2 flames in it.

--Code changes
 -Use raw array of floats in OpenCL for perlin noise, rather than float3/double3.
 -Add some default cases to dc_perlin.
 -Redo singleton pattern yet again. Deriving from a templated Singleton<T> class was creating a separate instance per module. Now only one instance of each type will ever be created and it will be wrapped in a shared_ptr which guarantees its deletion as main() exits.
