22.0.384

Added a new member to UNI_Category::ToolInfo to support adding custom tool scripts for node types. Custom tool scripts can be added in UNI_Category::nodeTypeToolInfo() by calling ToolInfo::setScript(). Classes which inherit from UNI_Category will need to be recompiled. Since, UNI_Category.h is a new header shipped with Houdini22, its probable that this change will not affect most HDK users.

ABI break for clients using UNI_Category.h prior to Houdini 22.0.384.
