Shifted a lot of pin adding functionality from Blueprint Details customizion to the nodes themselves or BlueprintEditorUtils.
#jira UE-11334 - Dragging a pin to a node that can add pins (function entry/exit, custom events...) should add a pin of the type to the node.

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!
