LIVE: BP: Memory leak when opening blueprints

When opening blueprints, there is a potential memory leak occuring as the blueprint editor opens

1. Open task manager, switch to processes
2. Open Editor (QAGame)
3. In the task manager, find UE4Editor.exe, take note of the amount of memory used.
4. Open PlayerPawn blueprint
5. Select task manager, take note of memory used in task manager
6.  Close the blueprint editor, take note of memory used in task manager
7. Open the same blueprint, take note of memory used in task manager
8. Close the blueprint editor, take note of memory used in task manager
    
   Results:
   Each time the blueprint editor is opened, the memory in use jumps, when it is closed, significantly less memory is returned to unused. The more a blueprint is opened, the more memory will be taken for the editor overall until the entire editor is closed again.
    
   Expected:
   When a blueprint is open, the memory spikes upwards, however when the blueprint editor is closed, that used memory returns to being unused entirely.

Frequency:
5/5
