Previous version most of the time just got "stuck" on floating windows,
switching back and forth between floating window and tiled window underneath.
This was because "magic point" was left in the same position and thus next
navigation commands selected the same windows over and over again.
Now the "magic point" is moved around such that it doesn't overlap with the previously selected window,
and there are more complicated rules to make navigation between floating and tiled windows more natural.
The original behavior of navigating between tiled windows is preserved almost precisely.
Previous version also prevented switching windows using focusUp/focusDown
when in Full layout. Now there's a special case that handles such situations.
In the original code, when a GridSelect is shown, user has to use
keyboard to cancel it (ESC key by default). With this field added,
when it is set to True (the default), mouse click on empty space
can cancel the GridSelect.
_NET_CURRENT_DESKTOP doesn't act on a specific window and its ev_window
is set to the root window, but the root window is considered unmanaged
so this would be caught by the "not member" guard and ignored. We need
to move the guard a bit further down.

For ease of use, provide `fixSteamFlicker` as a pre-packaged
`floatConfReqHook` that can easily be added directly to a
`handleEventHook`.
Also, for discoverability, re-export it from X.U.Hacks.
Implements a replacement event handler for 'ConfigureRequestEvent' to
work around misbehaving client applications such as Steam, URxvt and
others that try to restore their absolute window positions. Primarily
motivated by the Steam client being almost completely unusable in xmonad
lately.
(I've been running this code in my xmonad.hs for other purposes for
years.)
More specifically, ignore ClientMessageEvents for unmanaged windows.
Steam likes to send _NET_ACTIVE_WINDOW requests for all its windows,
including override-redirect ones, which used to result in an invocation
of `windows` with a no-op Endo—equivalent to a call to `refresh`. But
this refresh makes Steam close its menus immediately.

This contains a breaking change for readHistory, writeHistory,
historyCompletion, and historyCompletionP to take an XPConfig, so they
are aware of this choice. While the latter two are exported, it seems
unlikely to affect many users.
