Updated version config to mirror that of milk

Created ImageStreamIO_config.h.in that defines project name & version
params.
Version gets set in CMakeLists.txt and config header gets dynamically
generated.
Updated ImageStruct.h to include ImageStreamIO_config.h.
Added ImageStreamIO_config.h to .gitignore.
