#Branch UE4
#Proj BlueprintGraph, GraphEditor, Kismet, UnrealEd
#Summary Added code to navigate the users IDE to native functions and variables. Added options in the graph and myblueprint node context menus to navigate to the native code they represent.
#Add Added function FSourceCodeNavigation::NavigateToProperty to locate and open the header file where the variable is defined.
#Add Added function FSourceCodeNavigation::NavigateToFunction to locate the source code from the symbolmap and open the IDE at the definition location.
#Change Moved the code used to determine the correct modulename from FSourceCodeNavigation::GatherFunctionsForActors to FSourceCodeNavigation::FindClassModuleName so other functions didn't have to replicate the code.
#Change added Goto Code Definition for native variable nodes and native call_function nodes in the blueprint graph node context menu.
#Change added Goto Code Definition for native variables in the myblueprint node context menu.
#Add Added GotoNativeFunctionDefinition, IsSelectionNativeFunction, GotoNativeVariableDefinition and IsSelectionNativeVariable to FBlueprintEditor so the context menu actions can call these functions to goto source code.
