Fix issue 202. No cursor icons for RemoteApp 

Pointer updates are part of the base RDP protocol MS-RDPBCGR specification and do not include window information like those from the RAIL specification MS-RDPERP do.  To make pointer updates work, we need to keep track of which window has focus and then apply pointer updates to that window.  This appears to be easy to do, just watch for X11 EnterNotify events and update the window field of the main RDP structure.  I had some concerns that a window might receive an old pointer update for some other window due to network latencies, however, the RDP server seems to always send down new pointer updates whenver a window takes focus.
