The default hasher for UT_ArraySet, UT_ArrayMap, and other UT subclasses now defaults to hboost::hash instead of std::hash to fix a performance issue on Windows for integer/pointer keys while also ensuring consistent cross-platform results.

For old that created custom hash specializations with these classes, implement a hash_value() overload instead for your type.

There's a new, experimental and partially incomplete image handler for OpenEXR images avaialble in Houdini. This driver uses OpenImageIO to read/write .exr files. It is mostly disabled, since the code is still a workin progress, however, it can be enabled by setting HOUDINI_OIIO_EXR.

This new image handler has some advantages over the old driver, primarily in its handling of multi-part EXR images. If the old driver detects a multi-part image, it will now fall back to the OpenImageIO driver to load all the sub-images.
