Some terminals don't report which buttons are involved in some mouse events. For example, the urxvt protocol (http://www.huge-man-linux.net/man7/urxvt.html section "Mouse reporting") does not report which button has been released. In this case libtermkey reports button 0 (http://www.leonerd.org.uk/code/libtermkey/doc/termkey_interpret_mouse.3.html) The function forward_mouse_event completely disregard the case button==0. On press events, there is not much we can do, and we keep the current behavior which is dropping the event. But on drag and release events we can compensate the loss of functionnality by remembering which button was last pressed. Fixes neovim#3182 for urxvt.

I tested that #3182 still works in xterm as well.
