Title: xfreerdp: send extended mouse events, using common button values for now

This lets the back/foward mouse buttons work.

I dont think there's a standard for what x11 events clients receive based on mouse (and its driver), xserver config, or tweaks by linux distro's, so I picked some values that I thought were reasonable.
