hidnplayr 49830b7fd4 Update to the VNC-client
The new client uses a thread to receive and parse all incoming data from server.
Standard graphics mode is 8BPP but you can use 32BPP if you uncomment it in raw.inc 
Mouse works, keyboard doesnt (yet)
No encryption supported yet.
Cursor is drawn remotely.
