6ed76af210 Restructure vulkan init code 
Vulkan init code was resturctured so that "temporary" structs (e.g.
vulkan "info create" structs) are discarded after they are used.

3b11564a4a Addendum note to previous commit 
It was assumed in the previous commit's message that the shader data was
stored on the stack. In actuality, the usage of std::vector<char> uses
dynamically allocated memory, which means the data should be on the heap
not the stack.
