Add note about exceptions and UniqueHandle

Browse Source 
It seems that the use of UniqueHandle requires that exceptions be
enabled. Added note to this section regarding this.

For each function which constructs a Vulkan handle of type ```vk::Type``` Vulkan-Hpp provides a second version which returns a ```vk::UnqiueType```. E.g. for ```vk::Device::createBuffer``` there is ```vk::Device::createBufferUnique``` and for ```vk::allocateCommandBuffers``` For each function which constructs a Vulkan handle of type ```vk::Type``` Vulkan-Hpp provides a second version which returns a ```vk::UnqiueType```.

there is ```vk::allocateCommandBuffersUnique```. there is ```vk::allocateCommandBuffersUnique```.
Note that using ```vk::UniqueHandle``` comes at a cost since most deleters have to store the ```vk::AllocationCallbacks``` and parent handle used for construction because they are required for automatic destruction.

# Custom allocators # Custom allocators
Sometimes it is required to use ```std::vector``` with custom allocators. Vulkan-Hpp supports vectors with custom allocators as input for ```vk::ArrayProx``` and for functions which do return a vector. For the latter case, add your favorite custom allocator as template argument to the function call like this: Sometimes it is required to use ```std::vector``` with custom allocators.
