Feature to drag a file from Windows to Mac:

- On Mac client main thread is used for cocoa application in order to simulate drag.
- Send dragging file dir from Windows server to Mac client while dragging after switching screen.
- Dragging information sending is immature now (need to support multi files dragging in the future).
- Used Cocoa function to monitor dragg pasteboard.
- Changed Mac client to use another thread for event queue instead of the main thread.
- Change fileRecieveComplete to fileRecieveCompleted.
