[x11] Grab focus when the pointer enters the window

Browse source 
This is necessary in focus-follows-mouse environments (at least for
openbox, but it wouldn't surprise me if most other WMs behave the same
way) because the WMs don't set focus when the pointer is grabbed (which
XInput does before the WM sees the enter event). This is especially
important when the window is fullscreen on a multi-monitor setup as
there is no border to *maybe* catch the mouse before it enters the
window.
