Added TestForDDImageVersion.cxx to FindNuke.cmake so that we can work…

…out which version of nuke we are building against. This now gets appended to the '$CMAKE_INSTALL_PREFIX/lib/nuke${Nuke_DDImageVersion}'. This makes it easier to build and run against multiple versions of nuke.

Added init.py and menu.py so that the ocio nuke plugins can be setup with the NUKE_PATH searchpath, to make it easier to test and integrate into our toolchains.

Updated the INSTALL file to reflect these changes.
