WX: HiDPI: FrameAUI / Debugger

Changes:
  - MemoryWindow was cleaned up and gives more feedback on searches.

Some bugs were fixed as well:
  - A complex bug that allowed tearing off tabs and opening multiple
    copies of a debug panel which lead to segfaults
  - Another segfault related to right-click menus on code/memory views
    when those tools were floating in their own window.
