RemoteApp Support

1. Remove all uses of "localWindowOffsetCorr" variables, they added an extra layer of complexity and they are not actually needed to handle coordination of window position/size between
the local coordinate system and the remote one. This logic was causing issues in the case where the window was moved off the left side of the screen.

2. Update the xf_setWindowVisibilityRects function to offset the visibility rects as necessary when the window is hanging off the left side of the screen.

3. Stop sending mouse events when doing keyboard moves/sizes(as desired), and stop sending two mouse events for non-keyboard moves/sizes

4. Move location of new UTF8_STRING variable from previous commit

5. Refresh window and window shape for any window position/size updates, this helps keep the local and server windows in sync and works around some race conditions
