Fixes to Full Interaction

- Changes Full Interaction from suing SendNotifyMessage to SendInput.
- Changes from BringWindowToTop to SetForegroundWindow,
SetForegroundWindow is a lot more reliable.
- Combined, these changes fix clicking with Explorer, Unity, Task
Manager (requires Admin), and MS Paint :D No Click+Drag yet however.
