Debugger now checks for a valid graph before dereferencing it. We may not have initialized the graph before the debugger is set up, so we lazy-initialize the root node pointer.
TTP# 338513 - CRITICAL: Regression: BEHAVIOR TREES: CRASH: When opening
reviewed by Andrew.Rodham, Max.Preussner

Added editor-only functions to allow nodes to override their in-editor icon display.
Added Blueprint icon to show which nodes use Blueprint for their logic.
Hooked up new icons to Editor style.
Added missing Blackboard icon.
TTP# 337682 - [ART REQUEST] New Icons for behaviour trees

Tweaked and reworked the BT editor to allow for multiple modes (like the Blueprint Editor).
If a behavior tree uses a Blackboard, that blackboard is editable in the same asset editor, under "Blackboard mode".
Fixed a number of issues with re-focussing the BT debugger (and some issues that arose when switching BT editor modes). Debugging info should now be properly displayed when selecting AIs, switching modes, starting up the BT editor while playing etc.
Fixed a breakpoint bug where debug pause would be toggled rather than enabled, causing the game to run for a short time.
Added new icons for BT & BB modes.
Added various new guards against nullptr dereferences.
Displayed Actor label rather than FName when choosing actors to debug.
TTP# 337108 - Behaviour Tree Editor: Integrate Blackboard Editor into Behaviour Tree Editor

- merged over from Fortnite branch
- includes adjusting all game projects that use AI code
- contains a nasty AIModule <-> Engine circular dependency. To be removed ASAP

Settings specific to Anim, Blueprint and Material Editor should probably be broken out into their own settings classes in the respective modules at some point. It feels a little strange that the GraphEditor needs to be aware of specific pin and node title types. At this time I did not want to refactor the existing graph editors though, and since many of the properties are currently being shared, pulling these settings out of UEditorUserSettings is at least a good first step. In the future I would like to see settings sections for specific graph based editors instead of having a generic 'Graph Editor' section that is shared by some or all editors.
I exposed various color settings in the UI as many users seem to be quite excited about customizing their Editor. If you think that some settings should be added or removed, please feel free to make any desired changes or let me know. Thanks!

#summary Rename Trunc, Round, Floor, Ceil to TruncToInt, RoundToInt, FloorToInt, CeilToInt. Added *ToFloat versions. Repeated for FGenericPlatformMath and all derived classes for all platforms wherever applicable. Corrected comment in Fractional and added Frac() which does HLSL-style fractional (x - floor(x)). Checked for compilation on all projects (with cooking levels wherever applicable). Didn't change Fractional to Frac, this will be done in second commit.

#Add SNodePanel::SNode::FNodeSet typedef for conveniance and clarity
#Change Changed SNodePanel::MoveTo to take an FNodeSet as an exclusion filter on the moved nodes, once moved nodes are appended into this set.
