Added a new anim node: AnimNext Parameters. This injects parameters into the AnimNext stack for all leafwards nodes.
Added a new way of binding to parameters on anim nodes.
- Added indirection to UAnimGraphNode_Base to allow different 'binding types' to be authored by deriving from UAnimGraphNodeBinding
- Added new binding type for AnimNext parameters
- Moved existing binding code (inc UI widget creation) into UAnimGraphNodeBinding_Base
- Binding types can be selected on a per-node or per-anim BP basis
Reworked FParamStack API a little
- Allow for better error checking when pushing/popping stack layers. Pushed layers can now only be subsequently popped by passing in the handle of the pushed layer.
- Standalone layers are now wrapped in an opaque handle rather than returning a unique ptr
- GetParamData APIs now perform more involved type checking, allowing derived object types & type conversions to be implemented
Improved parameter type sandboxing for automated tests. If running low-level type tests while execution was happening on another thread, the editor could crash because of invalidating already-existing types.
Lots of other small fixes to get workflows nicer and end-to-end functionality working

Added a new animation graph node that hosts its own UBlendSpaceBase. Modified UBlendSpaceBase to allow for pose links to be evaluated as the sample points.
The new blend space graphs can be spawned from existing UBlendSpace and UBlendSpace1D assets, or they can be created from scratch, or they can be converted from existing blendspace player nodes via the context menu.
Fixed anim node conversion functions so that their transactions work correctly.
Updated FBlueprintEditorUtils::IsGraphNameUnique to allow it to work with any object as the outer, not just UBlueprint. UBlueprint still has a special case for functions and events. This is to support GenerateUniqueGraphName within a scope (e.g. an outer graph).
Formalized the concept of 'node sub-graphs' (as well as the composite node pattern a little). Previously a number of known node types that contained sub-graphs (e.g. UK2Node_Composite) had special case logic for dealing with node/graph deletion etc. Now any node can opt into this behaviour via the GetSubGraphs() override.
Added status bar readouts for the blendspace grid, so we dont have to stuff the prompts into the tooltip any more.
Moved anim BP related APIs out of FBlueprintEditor. They are always used via FAnimationBlueprintEditor.
Refactored graph title bar widget creation out into a function to allow other document tab factories to create it.
Altered breadcrumb trail click callbacks and SMyBlueprint::ExecuteAction to always JumpToHyperLink rather than calling OpenDocument directly. This allows unknown (to FBlueprintEditor) document types that reference objects to be correctly jumped to using the breadcrumb trail. Derived asset editors (i.e. FAnimationBlueprintEditor) can intercept the JumpToHyperlink call to ensure that the correct document is presented (i.e. the correct tab payload is generated).
Instead of making yet another bunch of duplicated code for handling the various alpha blend options, refactored this into FAnimGraphNodeAlphaOptions (for editor code) and FAnimNodeAlphaOptions (for runtime code).
Added OnCopyTermDefaultsToDefaultObject for per-node copying of default values from editor node to runtime node, rather than another special-case in the compiler.
