[2.2.0 GUI] Drag and drop support

[BigBoiCJ]

• Added Drag and Drop support, by dragging a folder on SAC's window (Drag & Drop #70, massive thanks to @MasonGuinn for the PR! Requested in Drag/Drop game folder onto app window #68)
  • The code structure was changed a bit with this PR. No features have been altered.
  • Added tkinterdnd2 (v0.4.0+) as dependency. This is needed for the drag and drop support.
    • This could break things, but from my testing, everything worked fine. Please report any bug you encounter!
• SAC will now remember the last (parent) folder that you selected, which should make it faster to crack games later if you store them in the same location! (Drag & Drop #70, thanks to @MasonGuinn)
• Added a warning for 3rd crack approach not working (3rd crack approach (Only create config and put in SAC directory) acts like the 2nd #62)

SteamAutoCracker GUI requires a 64 bits Windows computer.
